Do your job

I've paid up my account a few months ago and haven't received my paid up letter from vodacom and my account still reflects on the credit bureau. I've contacted them in Jan2020 and still waiting for my paid up letter I've been contacting them every month and still havent received anything even though the consultants said its paid up on the system and they going to escalate it and here I'm still waiting. I'm in the process of paying a company to get it removed from the ITC but still need the paid up letter from vodacom seeing that they never sent anything to the Credit bureau after they said plenty of times they going to do it. And now you can't get through to anyone at the call centers
