Same sh*t, different month

FNB hashares proved to me once again that I should have left them when I had a chance to. Im experiencing the same problem again in a period of 60 days. Went to wimpy in JHB, paid with my card and the ****** thing took money from my account even though the machine said declined. I was told to swipe again and I refused. I said I'd rather pay cash for the item cause I don't want experience the same thing in one day cause of past happenings. I was told that money would reverse itself into my account. I'm still waiting for that to happen. I went to ghandi square branch to report the matter and the *********** branch controller told me she can't help me. I told her it's not the first time this is happening and I told her the process I followed the last time. The first time it happened, I fought with FNB for a month for my issue to be resolved. I'm not willing to wait another period cause of ******* systems used by banks and merchants. I need my money in my account then I'll be moving to another bank. I can't take this nonsense anymore.
