Unhappy customer

On the last day of June 2024 I had no funds on my account so my MTN debit for my cellphone contract did not go through then MTN sent me a link to pay via @pay so on the 13th of July I successfully made a payment then End July I was double debited I have sent numerous emails attached with the detailed proof of payment but I have not even once got a positive feedback after so many months my issue Is not resolved,I have been running after them.I went to the MTN stores they are not helping.I would not recommend MTN contacts I can not wait for mine to expire!
