Frustrated with MTN service

I have 2 contracts with mtn - I want to terminate both contracts as I'm unemployed. I have tried for the last 6 months to sort it out and I have been struggling to do so. I have been paying as per their instruction to terminate but nothing gets done about it - it just gets offset with my main number. Please I need your urgent assistance to settle this matter - according to MTN (Called 135) on Friday dated 29 April 2022 I had to pay R1833.07 to cancel and terminate contract *** and I did so - sent POP to them to indicate that payment has been made and the beneficiary reference number did not want to take this number but my main number which is ***. I asked them (via mail, *** & ***) to allocate the amount to the *** and the next day, the Saturday I was sent a text message indicating that they did receive the payment and it will be allocated to my main number!! I am so frustrated with their service, I have spent time, airtime, data, - back and forth to sort it out but clearly they don't have my best interest at heart. I advised them that I have been UNEMPLOYED since October 2021 and want to do the right thing by terminating both contracts and want to revert my main number *** back to Pay as You go. Please I am financially struggling, and have been unsuccessful with employment and want to settle this matter as soon as possible. I want both contracts terminated and want to change service providers as it is clear, MTN has no empathy regarding my matter. I'm trying to do the right thing but they are making my experience very difficult!! Details as follows - BA***: CELL: *** CELL: ***
