Poor customer service care

I had a loan with D.A which was fully paid and supposedly closed in November 2018. Upon checking my credit report this loan was still reflected as active. I then contacted D.A to finalise closure and have them remove it from the credit bureau as active. This was in 2020. Upon checking my credit report today I found that it is still reflecting as active and that I owe them R865?! Tried calling all their numbers available on the website only to be made to hang on for 10 min at a time. Still have not manage to get hold of a consultant after 6 calls which is ridiculous!
