FNB Card Division - *********** and Arrogant

After the ***** up with the FICA registration in November (a system problem!!!) FNB Card Division happily carries on with their *********** and arrogant dealings. *********** why? My automatic payment on 1 December was miniscule, not the full amount I've always paid. I immediately queried that with a private banker, and she came back the next day confirming that only the minimal 5% had been charged with the debit order. She also confirmed that my profile showed that the full amount should have been debited. Apparently it was a system error!!!! I was told that if I paid the other 95% that day there would be no interest charge, and I paid immediately. But of course, Card Division's incompetence overrules everything and I was charged interest. So I phoned again, and was told that they are aware of the system problem on 1 December, and that the interest will be reversed. When I queried why this hadn't been done already since they had been aware of the problem since the beginning of the month, I was told that it will be done....... When, dear ***********s? Arrogant why? For both the FICA system problem, and now this one, there hasn't been any correspondence acknowledging it, let alone an apology. I've had it, can anyone recommend a credit card company that is run by business people with a customer service attitude?
