Credit record

Kindly take note I'm not happy with FNB services whether is call centre,KYC care centre, i have been at every department of FNB without any assistance regarding my credit record and they are unable to fix, because they told me i need to be in contact with Transunion and Experian of which they did explain and clarify my credit record and the once i was talking about or querying of an amount of R105 000.00 they are not aware of it.
