Horrible Customer Service

I have sent numerous email since 22 October and to date I have not received a single response. I am going abroad and changed my banking details, received and email to advise that I need to have my new bank account verified and they require a letter from my bank. That was was sent on 22 October and again on 05 November and still have not received any feedback and there is no way to call them.

This service is PATHETIC.
