Credit card division is ***********

I was offered the Titanium account, a few months after the change from the Gold acc the bank contacted me to say that I had costs on my credit card which were never transferred to the new account. I repeatedly requested a statement at the time and never received any. The bank however deducted the money from my account to which I lodged a complaint. After an investigation the bank admitted their mistake and sent an email stating that they had a system glitch that recreated closed accounts and billed against these. My money was returned at the beginning of this year. At the start of April the bank started calling me 3 times a day claiming that I owed them the disputed amount. After providing them with their email stating their mistake they decided to deduct the money once again from my account. The staff that I dealt with all understood and were sympathetic and promised to resolve the issue but never did.
