**** of a Company

This is a **** of a company. They have been sitting with a debt I don’t even owe from MTN for almost 3 years now and they have never contacted me. I had to find out myself that I have been handed over from a measly R1200 which accumulated interest and is almost at R2000. I paid the amount to Saya recoveries almost 2 months ago after finding out, send the proof of payment multiple times on multiple channels but I still appear as owing and blacklisted at MTN.
