BAD CUSTOMER SERVICE

A 1start is even to much for MTN, I am so frustrated and furious with MTN customer service back and forth for the past few months, I am having monthly problems with my MTN account, even after sending nurmerous emails and visiting their branch. I have been charged thrice the month of february and even sending my statements to their customer with my bank statements i was told no refund due as I am owing for August 2024 however the payment was made on their app and when making payments in the branch i was told there is no arrears besides my monthly installment, My service was suspended prior and the consultant explained there is no way I can be in arrears for over 90 days with my service being on and also nowhere did i receive a statement showing i am behind with payment because I use their app to make my payments ,I was also told my Debi check was cancelled on their system and had to reactivate I am exhausted of the back and forth fighting for my R905.21. I WANT TO CANCEL URGENTLY WITH MTN ALREADY
