My account hacked and compromised

This was your last attempt to assist me (below) in resolving this issue (10/4/2015) which did not receive a response? It is now the 15/5/2015 and I have received no correspondence whatsoever from you, and no communication from Vodacom. How much longer do you propose to treat this matter with total contempt - and no end in sight? (Despite the many concerns I have brought to your attention each one of them has never been addressed?) Your lack of understanding or desire to resolve this issue is intolerable and I require your urgent feedback in this regard.
