MTN Contract

On the 5July I contacted MTN Contact Center and request my contract to be cancelled for my TOP up package with cell Number ***, as I don’t want to renew it, I was told that it will be cancelled on the 5th August 2023. Today the 08 August when I’m doing the follow-up I was told that, the request was received on the 5 July but MTN did not cancel the contract, I was sent from pillar to post when asking why, and whose fault is it as I have done my part and inform them that I’m no longer interested in renew the top up contract. Can anyone please tell exactly what is happen with your company because now you will keep on deducting on my bank account of which I have told you to cancel that package. Can you please give me the confirmation in writing that you have cancelled that package as per my request and sent it to my email address.
