MTN SA - ******* and *****s!!!

My account has been suspended 3 times this week due to apparant non-payment even though I paid my account on 25 April 2023. Every time I call I am told that my payment has not been allocated and that I need to submit the proof of payment. Each time after the call I get an sms stating that "a payment arrangement has been made and I promised to pay the outstanding amount today". This after I paid the account due on 3 May 2023 on 25 April 2023 already. This morning my account was suspended yet again. When I called I was told the payment was not allocated and my account cannot be unblocked because I failed to adhere to the payment arrangements. I have now in this week sent MTN the proof of payment 5 times, called 4 times and my account is still blocked. Today I requested to speak to a manager and was told I would get a call in hour our. Still waiting. How is it possible to take over two weeks not to allocate a payment. I have gone as far getting my bank to confirm in writing that payment was made on 25 April 2023 and has gone through. I followed all the rules, paid my account way before due date and now I am penalised for their incompetence. I cannot make any calls and I do not know what to do anymore. I feel like opening a case of theft and ***** as MTN has ****** my money. I paid on time and yet I have no services! This is the worst service I have experienced in many years. They are absolutely useless!!
