Incorrect Listing on ITC

I had a loan account with Capitec bank where I settled and paid up the full loan amount on 15 December 2015. I also did receive a settlement confirmation letter. Only to find out yesterday when I tried to apply for vehicle finance at FNB I was advised that I have a outstanding loan with Capitec bank. Further to this I was also advised that I had another outstanding multi loan with Capitec bank, which this was an error on their side which they also gave me another confirmation that there was no outstanding amounts due by me. The service was pathetic when I went to their Rosebank branch this morning trying to resolve this issue for 3hours, only to be told by the Branch Manager that they did send confirmation to the credit bureau to update the settlement of the loans. I requested for the branch manager to help by sending me an email confirmation with my query details and a brief summary of what is going to be done to help me resolve this issue. He advised me that its not their company policy to email customers. I must take my ref number and wait for feedback, he then explained that it is the credit bureau that didn't update my profile and its not Capitec's fault. I am highly disappointed in the way my query was handled and having *********** people dealing with my query.
