1-Download and install fiddle (http://www.telerik.com/fiddler) (enable - Tools > Fiddler Options > HTTPS tag > Decrypt HTTPS trafic)
2-Create a new desktop application (note ASP.NET call cant be traced, because running under different user account, http://www.telerik.com/blogs/capturing-traffic-from-.net-services-with-fiddler)
3-Fire up VS, Add the WSDL url aka hxxps://paycenter.piraeusbank.gr/services/tickets/issuer.asmx via PRJ (r-click click) > Add Service Reference

4-edit your app.config
remark customBinding tag and customBinding endpoint
5-on your desktop application form paste :

JavaScript: 
//used to calculate md5 from password
public string CalculateMD5Hash(string input)
{
	// step 1, calculate MD5 hash from input
	MD5 md5 = System.Security.Cryptography.MD5.Create();
	byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(input);
	byte[] hash = md5.ComputeHash(inputBytes);

	// step 2, convert byte array to hex string
	StringBuilder sb = new StringBuilder();
	for (int i = 0; i < hash.Length; i++)
	{
		sb.Append(hash[i].ToString("X2"));
	}
	return sb.ToString().ToLower();
}

6-add a button to form, on button event write

JavaScript: 
private void button1_Click(object sender, EventArgs e)
{
	string ret_MerchantReference = "7"; //your order_id here

	ServiceReference1.TicketRequest x = new ServiceReference1.TicketRequest();

	x.AcquirerId = 1;
	x.MerchantId = 2;
	x.PosId = 3;
	x.Username = "3";
	x.Password = CalculateMD5Hash("4"); // md5 - "4";
	x.CurrencyCode = 978; //978-euro
	x.Amount = 10;
	x.MerchantReference = ret_MerchantReference;

	ServiceReference1.TicketingServiceSoapClient t = new ServiceReference1.TicketingServiceSoapClient();
	ServiceReference1.TicketResponse y = t.IssueNewTicket(x);
	Console.WriteLine(y.ResultDescription);
}

7-now, using fiddle, sniff the request

formatted :

JavaScript: 
//test
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
	<IssueNewTicket xmlns="http://piraeusbank.gr/paycenter/redirection">

		</Request>
	</IssueNewTicket>
</s:Body></s:Envelope>

8-create a new PRJ! following the https://www.roelvanlisdonk.nl/?p=1893 directions
9-Paste&Compile&Execute :

JavaScript: 
private void button1_Click(object sender, EventArgs e)
{
	Execute();
}

///
/// Execute a Soap WebService call

public void Execute()
{
	HttpWebRequest request = CreateWebRequest();
	XmlDocument soapEnvelopeXml = new XmlDocument();
	soapEnvelopeXml.LoadXml(@"<?xml version=""1.0"" encoding=""utf-8""?>

                                </s:Body></s:Envelope>");

	using (Stream stream = request.GetRequestStream())
	{
		soapEnvelopeXml.Save(stream);
	}

	using (WebResponse response = request.GetResponse())
	{
		using (StreamReader rd = new StreamReader(response.GetResponseStream()))
		{
			string soapResult = rd.ReadToEnd();
			Console.WriteLine(soapResult);
		}
	}
}

///

public HttpWebRequest CreateWebRequest()
{
	HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(@"https://paycenter.piraeusbank.gr/services/tickets/issuer.asmx");
	webRequest.Headers.Add(@"SOAP:Action");
	webRequest.ContentType = "text/xml;charset=\"utf-8\"";
	webRequest.Accept = "text/xml";
	webRequest.Method = "POST";
	return webRequest;
}

the result is :

JavaScript: 
//test
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

                0</MinutesToExpiration>
        </IssueNewTicketResult>
        </IssueNewTicketResponse>
    </soap:Body>
</soap:Envelope>

time to make the ASP.NET flavor on server, because server IP, white listed to bank!

running the same code on aspx the response was :

JavaScript: 
//test
<soap:envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:body>
    <issuenewticketresponse xmlns="http://piraeusbank.gr/paycenter/redirection">
        <issuenewticketresult>
            <resultcode>0</resultcode>
            <resultdescription>
                [TR]2xxxx3</tranticket>
                <timestamp>2016-01-01T11:53:00.3473139+02:00</timestamp>
                <minutestoexpiration>10</minutestoexpiration>
            </resultdescription>
        </issuenewticketresult>
    </issuenewticketresponse>
</soap:body>
</soap:envelope>

now we have to read the tranticket from SOAP response^ and submit a form to gateway

JavaScript: 
string resp_tranticket;
var doc = XDocument.Parse(soapResult);

XNamespace s = "http://schemas.xmlsoap.org/soap/envelope/";//Envelop namespace s
XNamespace bhr = "http://piraeusbank.gr/paycenter/redirection";//Response namespace

foreach (var itm in doc.Descendants(s + "Body").Descendants(bhr + "IssueNewTicketResponse").Descendants(bhr + "IssueNewTicketResult").Descendants(bhr + "TranTicket"))
{
   resp_tranticket = itm.Value.ToString();
   MerchantReference.Value = soapResult; //set the resp_tranticket value to #MerchantReference HTML input#
}

then, submit the HTML form!

JavaScript: 
//test
<form action="https://paycenter.piraeusbank.gr/redirection/pay.aspx" method="POST" runat="server">
    <input name="AcquirerId" type="text" value="1" /> <br/>
    <input name="MerchantId" type="text" value="2" /> <br/>
    <input name="PosId" type="text" value="3" /> <br/>
    <input name="User" type="text" value="4" /> <br/>
    <input name="LanguageCode" type ="text"  value="el-GR" /> <br/>
    <input id="MerchantReference" name="MerchantReference" runat="server" type="text" value="0" /> <br/>
    <input name="ParamBackLink" type="text" value="p1=v1&amp;p2=v2" /> 
</form>
