I want my money back. Your incompetence is infuriating

Both my MTN Contracts *** and ***) were due to EXPIRE on the 11/07/2024. On the 11/06/2024, I called MTN Cancellations (from ***), informing them that I did NOT want either of my contracts renewed. Both contracts were due to expire in exactly one month from the 11/06/2024 (the day of my phone call) MTN was instructed, on the 11/06/2024 to CANCEL both contracts on the 11/07/2024. THIS WAS ONE MONTH'S NOTICE. Both contracts were CANCELLED on the expiry date but then MTN reactivated ***. WHY WAS THE CONTRACT REACTIVATED??? Then, on the 01/08/2024 MTN billed me R722.50 for a contract which they had not successfully cancelled. This resulted in me having to call MTN AGAIN, to cancel the reactivated contract. On the 01/09/2024, MTN billed me AGAIN (R639.62). WHY WERE BOTH CONTRACTS NOT CANCELLED ACCORDING TO MY TELEPHONIC INSTRUCTION? This instruction was NOT an early cancellation. I informed you on the 11/06/2024 that when the contracts reach their expiry, CANCEL. I want my money back!!!! DO YOU UNDERSTAND? This was NOT an early cancellation. REFUND ME.
