Contract Upgrade without Permission and i requested cancellation and it did not happen

I have multiple contracts with MTN. On February 28, 2025, I called to cancel one of the numbers. The representative I spoke with confirmed the cancellation and then checked on another contract that was due for an upgrade. He asked if I would like to upgrade, and I rep**** that I needed to consult with my son, who is using the SIM card. I requested that he call me back later, and he agreed before ending the call.

However, shortly after that, I received an SMS indicating that the contract had been upgraded without my permission. I called MTN for clarification, and they informed me that although the upgrade had been reversed, they did not cancel the contract.

On March 7, a consultant contacted me regarding the same issue and confirmed that the contract had been canceled. However, on March 10, another consultant called me to offer an upgrade on that same contract. I informed her that the contract had been canceled, but she insisted it was still active. When I requested that she cancel it, she hung up on me.

I want the contract canceled effective February 28, 2025, as I initially requested.
