Supersonic not refunding my money

I cancelled my prepaid fibre contractual agreement with MTN Supersonic in July 2024 and submitted the required one calendar month notice of cancellation. During the month of July and August 2024 I had contacted Supersonic multiple times to ensure that the cancellation was on track, and they had assured me that my account would not be debited. Yet, they still debited my account in August 2024. I immediately contacted Supersonic and informed them of this error.

To date after multiple attempts of following up I am still waiting on my refund. It is evident that they are quick to deduct and not resolve or refund where appropriate. Having to spend so much money on airtime (phoning and having to hold 30 minutes each time just to try to speak to a customer service agent and receiving conflicting or no feedback or being cut off and having to phone again) to have my own money returned to me that was incorrectly debited is appalling, stressful and not to mention a waste of time.

I followed due process, and I have yet to receive my refund. I want this matter to be resolved urgently, and my money refunded as this is *****ulent. I will be lodging a formal complaint with ISPA if I do not receive my money.
