Malice and failure to help customer

i am submitting a matter for the second time now about nedbank failing to get my credit profile updated. i paid credit card and it has been almost two months trying to get them to update my profile. after listing R35000 as monthly instlallment thus pushing my affordability out still they cannot solve this. i need this matter to be resolved. how does outstanding balance become your monthly installment. This is on XDS and i am not going to waiste my time by completing forms for ITC. i did not list any adverse information so nedbank deal with this matter. this conducted and treatment re our credit profiles leaves much to be desired.
