ABSA vehicle finance

I’ve received the most appalling service from ABSA vehicle finance! Settled a vehicle in full on the 27th of December 2018, received the settlement letter and original vehicle documents, however I’m listed a defaulter and handed over! What makes matters worse is that I still receive statement for the settled vehicle, the most recent statement received was this month, and yet vehicle was settled in December? According to them they’re in the process of rectifying the listing and removing me from ITC. Just shocking as their internal mistakes affect my credit record!
