Most unprofessional, *********** customer service ever

have an month to month contract with you Mtn , and from the begining my account was n mess , as payment was supposed to be taken the closest to the 1st of the month , but then it went of on the 15th of each month, I then had a payment unpaid due to wrong date of payment , then I paid R450 to get my account up-to-date and also changed my payment date to the 4th of every month as I was told this is the closest date to the 1st, then a payment of R4999.99 went of on the 2and of September 2025 again payment went off to early and to much money was taken off .I have called the next day to lodge a complaint and request a refund, I have now today phoned for the 5th time and ever since I have not received any calls back or emails sent to regarding the process a week later the lady who assisted me said that the money was refunded in to my Mtn account which is not the type of refund I requested. I have lost my Samsung cellphone and had debit orders that is now unpaid and bounced , not sure who will be held responsible for my losses due to mtn's ignorance, I have also requested my money back Into my back account by the 5th of September 2025 ,but this was only processed on the 5th and till now I had no luck resolving this matter and still awaiting my Refund ..
