****med by MTN for 12 months

My late husband took a cellphone contract for me. He passed on January 2023. I went to Canal Walk Century City Entrance 3 Store where he took a contract to inform them after his funeral. I was told to bring his death certificate for the contract to be cancelled. I went back 3 times with death certificate. I was told. I am responsible for the account of the deceased. It's either I pay or I must bring ba the device. I didn't pay for the first month. My line was blocked. I had no other option. I had to pay it. It was the only number I had. Until 15 December 2023 I have have been paying R650 every month from January. Contract was finishing on the 15th December 2023. On the 15th November 2023 I was at the store to give notice. I was told to come before 12 December. I went to the store as I was told before 12 December 2023. I was told to come before 12 January 2023. I was told to call 135 It's only their legal department that they can access access deceased account. The person who helped me told me the store was wrong. They shouldn't let me paid the contract. She tried to put me through to MTN legal department. With no success. She sent email to them explaining the whole scenario. Ref no: ***. I have never heard from MTN since then. They blocked my line after that. I had to pay another R650 for the finished contract. Again ON 20 February 2024 my line is blocked. I tried to call again 135 was told to pay again. It's on month to month contract. When I explained to them. They put me through to 3x people. They all listen and hang up my call. I am feeling helpless and ****med my money for 12 months by MTN. I want my money back. I have proof of payment on my bank statement.
