i got another exception `The remote server returned an unexpected response: (400) Bad Request. — Kishore Kumar
Have you browsed to the WSDL on your endpoint - one of the errors says: "text/xml" was not supported by service - so maybe the endpoint isn't actually serving or is incorrectly specified — Charleh

Remove the messageEncoding bit from your basicHttpBinding binding. It's currently set to "MTOM" which doesnt allow text/xml transmission.
