FNB IS USELESS, NOTHING EVER GETS DONE

I request for FNB to close my cheque account and the have not closed. I specifically asked thar they close it for the purpose or opening a Premier account so that they can do my debit order switching and change me debit order date from the 25 to the 2nd of each month cause I have recently changed jobs. Reference CAS-***8-V7H0X1 was never actioned and I had to call again for another Reference CAS-***6-N8J6J6 that was never actioned with no reason whatsoever. I wanted to close the account so no debit order can come through as I won't have money paid on the 25th of the month. Now FNB did not close the account and debit orders went through that account on an overdraft and bank charges that I can never be able to pay. Had they closed the account as I asked non of that would have happened. You do not even deserve a star they way you have so much poor service. What is the point of creating channels of communication if you never going to action anything through them.
