MTN fixed Contract Can not be moved or Reimbursed for Payments

In 2022 I took a Moderm and Data contract with MTN via their call center sales people. I was not sent any contract to sign except to agree terms over the phone. Little did I know that I can not move the modern and the data plan as I it is a fixed deal. Due to work that I do, I had to move houses last year. That is went I found out that the data contract is fixed. I called MTN to move the data contract that I was referred to the WalK in Store. When I went to the store, I was told that I can not move the contract. The reason why I need to cancel the contract is the fact that I have been paying the contract for more than a year and I have not been able to use the date since I moved last year.

I called the Call Center, and I was told to visit the MTN branch. Upon visiting the branch, I was told that I will not be able to change the address. So I need to move the Route network to the new address or cancel the contract. I have since been told that I need to pay the cancellation fee of R1700 in order to cancel the contract.
