ANGERED!!!!!!!!

I do not want to rate African Bank, but I have to as without the rating I can't go further. I have had such bad service continued from their customer care department. Late yesterday afternoon I phoned them and requested a call back. i was still on the line and I was receiving a call back from them. How can you take a call, when you are still on the line? surely they can see you are on their system. i waited for about 3 and a half minutes and there was no answer from anyone to assist me, so I put the phone down. i then phoned again, managed to get off the line after once again asking for a call back. I then received a call back and waited this time for almost 11 minutes before a customer care representative came on the line to help me. Which actually was of no assistance at all. i could hardly understand what the representative was saying and she spoke sooooooooooooo slowly that it was awful. i have continued to complain about this issue and have now decided to take it to the ombudsman, as African Bank have **** to their clients. I have a "my world" bank account and if you swipe ten times in a month you get a R150 voucher, there are various vouchers you can choose. Last month I decided to change my choice and instead of getting the cashback which I was supposed to get they told me, this would pay my bank charges. I DID NOT ASK YOU TO PAY MY BANK CHARGES AFRICAN BANK. I ASKED FOR THE CASH BACK!!!!!!!! Surely it should be the clients decision how they use their cash back???? i would like an answer and I would like it to be displayed for every one for future reference. You have said in previous posts that I can only see your answer, well, actually their has been NO ANSWER!!!!!!! You have until the end of today, to give me last months cash back voucher, which is actually from the previous month, April, as we haven't received May's sms of as yet!!!!
