Standard bank card divsion is appalling

I app**** for an credit card increase and got it while still busy on the phone. Wow what excellent service I thought. A couple of days later while very busy at work, I received 3 phone calls which I couldn't answer. The following day I went to put petrol in my car to find out my accounts was blocked. After numerous phone calls and visits to the bank and emailing through my life history, only to find out my payslips don't match my accounts as my cards say Ms and payslips Mrs. Needless to say that all these documents were emailed 7 years ago and taken into the bank when I re app**** for a bond and had never been updated by the bank. Now I cannot get my credit card unblocked and had to borrow money for food and petrol. This is the most appalling service by the card division. Someone needs to sort this out now. I have been a good and loyal customer for about 20yrs and always pay more than is required by the credit card division.
