Poor Service

About two weeks ago I went to the Centurion Branch to check on my credit card. First I was surprised that despite the system indicating that no purchase are to be made with the card, a couple of transactions went through. How is it possible if the account is blocked that transactions go through? Secondly I increased my debit order. Today I got a letter stating that I gave instruction that the debit order be cancelled. This is the second time this happens to me. Last year also around January, I received a letter that I cancelled my debit order for my car. It took me two months to fix it and no explanation from ABSA. Who generates these letters? Is this an attempt by ABSA to discredit me? By the way I also increased by overdraft deduction. Can I expect another computer generated letter stating that I cancelled it? What a useless bank. Ive also left an email on their website interested in a car maintenance plan. Still waiting.
