Incompetence and harassment of ITC Business Administration

I have been sent a settling amount to pay to Massmart medical aid. The amount was paid in full on 17 April 2026. The phone calls continued that I still owe them the money. I discussed the matter with Bongani Maphisa who ensured me that he will sort the matter. I even received an email from him on 8 May to confirm that the account was settled and Massmart was informed. Yet, I still receive phone calls from ITC BA that I owe the money. I also received an email to this regard on 21 May. The level of incompetence at this company is beyond understanding. I have requested numerous times that the matter be sorted yet they still harass me with calls threatening that I will be blacklisted.
