i have paid up my FNB credit card in September this year 2021 ,to this date i have not received a paid up letter also FNB did not do credit update ,it still showing there i have active credit card account FNB which is over the limit which affecting my credit score negatively . Today i spoke to their call center agent they all lie does not know who can help me i spoken to customer service agent by John Makondo who **** and said he will transfer me debt review department they will definitely help me even though i was never under debt review also Johanna Maseko from debt review could not help transferred me collections even though i told her my account never been to collections it was always up to date she insisted that they will help then spoken Sibongile Silowe from collections who also could not help instead she **** and said i have 2 credit cards the one is closed other one is open, when i asked her credit card number she gave same one account number that i had settled and told me that fnb does not update itc i must do it my self and failed to answer to that when i asked for supervisor she hang up on me , and i cannot believe FNB is paying people to do just bad service .
