FNB IS USELESS

I have complained so many times I am exhausted snd beyond fed up. My bank account has about R12000 in it and it keeps being rejected for some obscure reason. I complained weeks ago and spoke to a man who said everything was fine with my account but would not stay on line with me while I tried for about the fifth time and was rejected AGAIN. Numerous messages came from the bank. My PIN was changed but that did not help. I was told someone would csll me within 24 hours. Nobody did. I know things are difficult right now but why make false promises then? And WHY does my card not work? I was approved on the bank site today and AGAIN my card wss rejected. AGAIN!! I AM SICK OF PEOPLE SAYING I ENTERED THE WRONG INFORMATION OR MADE ANOTHER STUPID MISTAKE! I am paying cash from now on. Oh, and the mistakes they made with my account ( sending R20,000 by MISTAKE and stopping a debit order by MISTAKE) have not been mentioned.They ruined my credit rating Great work FNB!
