BAD SERVICE

I am banking with FNB for more than 3 years know and never have I received such service in my life I phoned the call center on the 3rd of Feb to assist me as there is debit order that went off my account and I do not know of such an debit order, Ref number of the call Rb*** the lady informed me that she logged a call they will phone me back to tell me exactly what the debit order is for. On the 5th I phoned again as I still have not received a call back from them, spoke to someone else and they informed me the turn around time is 48hours they will phone me back before the end of the day. On the 6th I phoned again and someone else told me that the turn around time is 7 days this means by Wednesday the 11th I must have a answer. On Thursday the 12th I phoned again as I still have not received an answer from FNB the lady assisting me that day said she can not help me she can just log another call, The best is I must go into an FNB branch with the problem. On Friday the 13th I went into Nigel's branch where they helped me and returned the 1 debit order the other 1 they requested to return, today is the 27th and still I have no answer or debit order returned.
