Accounts/ billing

A debt collector called me about non- payment for a consultation at Medicross Roodepoort for an incorrect Date in July. I phoned medicross on November 17 2022 and spoke to Christo. He said he will look into it and get beck to me but never did. Same as before. 2 weeks prior they at least had the decency to email me about the account and I made the effort to fix. They gave the stupid excuse that the person that assisted me is on maternity leave. Is there no centralized system at medicross?? I was called by verified today, Christo and medicross still hasn't fixed the account. I did nit consult on the day you say I did. And the real consultation was paid by medical aid. Medicross/ Christo or 'Jennifer' fix this!! The day you say I owe you for I was at work the entire day!!
