Canceling accounts without permission??

I've been with FNB since I can remember... My mother has been with them forever, and so was her mother. But recently the service is pathetic. First of all, when you enter an FNB branch it's overcrowded because there are not enough consultants, and to top it off, the staff aren't very helpful. However, my main complaint is that they recently canceled my account without as much as informing me! It is my main and only account, so it was quite an issue to get that sorted out. I left FNB anyway and joined capitec, and I am so happy!
