Supersonic killed my internet

Worst ever internet data supplier. I signed up in October 2025 with MTN and Supersonic. All details were supp**** as requested. They never debit the first and second month and I had to pay manually. Now in December with holidays here I was cut off from internet access although I made another manually payment. I called the call centre where the operator tells me I have an outstanding amount of R700 due to a reconnection fee. This is outrageous as my payments was made. Worst ever experience with an internet supplier
