Incorrect accounts

For the past 7 months I have tried to get a Senior person at FNB Credit Card department to help me sort out my credit card mess up. After Clicks card closed down - they made a big mess of sending through 2 cards on their side and then just joining up the accounts without notifying me. When I questioned it - I was told some one will call to sort it out!! I have been continually harassed by them for payments which were not due at the time, I have had my savings account **********ly wiped out by them without permission - each time I put money into my savings account - they just wiped out each and every cent! and I am still waiting for some one there, after numerous phone calls etc to try and help me sort out their mess. It seems impossible to get anyone to try and help - all you hear is - I have no authority to deal with this matter!!!
