MTN Contract Cancellation Failed

Hi i have called MTN to cancel my contract which has already expired on the 6th October 2020. To be exact i called them the 14th October 2020 and spoke to AMANDA, my call was made early on in the morning so the CANCELLATION department was still closed but AMANDA sent through my request to as explained over the phone to me to cancel the contract on the 16th October 2020 i went into the MTN shop in PAROW CENTRE just to confirm it has been cancelled just to get dissapointing news that said i has not bee cancelled. I then whats app'd with MTN the SATURDAY 17th October NATASHA MAHLAKOLA called me back and said they cannot help me with the cancellation.

Today 22nd October i received my MTN bill with no proof of it being cancelled, i urgently need some assistance because i am UNEMPLOYED at this moment and do not know how i am going to pay this bill?
