Dishonest company

I took out a contract with the November 2021 for 24 months and was told that should I have issues with the fone I bought they will send a courier to fetch it I then had an issue with the fone I was told I must bring the fone to pretoria which was impossible.for me. My contact had reach its 24 months amd they are still.deducting which I do not understand why. I foned in and was told a bizarre story that I had no money in my account a certain month which was just ****. They stil.continuing to deduct regardless of me requesting termination. This company is a ****. Rather go to known outlets to get contracts. Can you please terminate and refund me my money. My refund number is ***. Please terminate.
