MTN Supersonic is the worst supplier of WiFi

We relocated to a new unit within the same complex at the end of August 2025. 30 August I called Supersonic (and I logged an online ticket) to move the existing wifi connection to the new unit. On Monday 1 September they called me and informed me that I must cancel the existing connection and apply for a new one, which I did not agree with, but did it anyway telephonically. I paid the full fee for September for the old connection that I had to cancel, and I paid for the new connection. They continue to charge me for October, because according to them, October is the notice month, even though they knew about about the cancellation since August 30th. I've sent multiple emails to info@supersonic.africa, accounts@supersonic.africa and complaints@supersonic.africa, but they don't even reply. They disconnected the new wifi connection (which is paid fully), because of the outstanding "notice month" of October. The "Customer Care" is non-existent. The don't even deserve 1 star.
