No service from Sharyl Naicker

I logged a complaint on the 31st May 2019 because I had a vehicle finance with MFC and sold the vehicle in September 2017 and obviously the account was settled. When I log onto my credit report it shows that I still owe you R155099 on the vehicle finance and that im paying R3578 as an installment every month. This affects my credit record and the credit I can apply for. I requested for a paid up letter and instead I received an email from (Sharyl Naicker) *** Stating a request has been sent to the credit bureaus and can take 21 working days to be updated but I will be furnished with a confirmation once updated. Since then no one has bothered coming back to me. I emailed Sharyl on the 3rd July asking for feedback since it was 21 working days at this point. By the 8th July I still had no response and emailed again and guess what? No response. Can someone please send me a paid up letter so I can submit this to the credit bureaus and fix your mess fixed since your own staff cant do it or give clients feedback.
