ANDROIDS KSOAP WDSL ERROR. PLEASE HELP TO FIND WICH PARAMETER IS INCORRECT!

USING KSOAPs LIBRARY, When debugging lines:

HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

[url removed, login to view](SOAP_ACTION, envelope);

I get this error:

[url removed, login to view]: expected: START_TAG {[url removed, login to view]}Body (position:END_TAG </{[url removed, login to view]}SOAP-ENV:Envelope>@3:21 in [url removed, login to view]@4145d440)

Could you check where of my parameters are faulty or wrong:

private static final String SOAP_ACTION = "WebBonusGXaction/[url removed, login to view]";

private static final String METHOD_NAME = "WSConsulta";

private static final String NAMESPACE = "[url removed, login to view]";

private static final String URL = "[url removed, login to view]";

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

[url removed, login to view]("web:Comercio", "013001");

[url removed, login to view]("web:Tarjetac11", "00001567112");

[url removed, login to view]("web:Fechatransaccion", "20160101");

[url removed, login to view]("web:Horatransaccion", "0000");

[url removed, login to view]("web:Pos_id", "1");
