DISGUSTING SERVICE ONCE AGAIN

I am literally over the service from FNB. I paid up my credit card which was handed over to Attorneys and received a letter from them that I would be removed off credit bureau within 7 days as stipulated by the NCA. I then put a complaint to FNB - ***Q which took 3 days for them to get back to me, to tell me that they cant help me. I then responded to them with a copy of the settlement letter from the Attorneys and they havent bothered to acknowledge nor respond to my email SERIOUSLY - I have had enough of the disgusting service that I have received from FNB over and over. I need this sorted, and yet they are clueless as what to do -
