ENOUGH MTN , ENOUGH

In November 2024 I received a call from whom I thought to be a MTN agent, He said that he was based in Pretoria and that a person, whom he named was trying to add another cell phone to my account, Did I give permission for this to take place? I said definitely not, so he said that he was sending me an OTP to stop this transaction, which happened, he asked me for the OTP ,which to my regret I gave him, that was the end of the story, till a couple of days later I received a message saying that R200 had been transferred to a new cell number which was not part of my contract, I immediately phoned the MTN ***** department, I was told that because of the type of contract nobody can mess around with it because it is bound. They also told me the new number was blocked, this satisfied me, I thanked the agent for the help. December I noticed that I was credited for airtime for 2 cell phones, I went into the MTN app and noticed that my account for December is a double installment, I tried to stop the payment but apparently it was too late, so once again I phoned the ***** department, I once again explained the whole story, I was assured that the case had been resolved and that the other cell number was blocked and I would be credited to my account, I explained that I am a pensioner and they had taken my whole pension , I was told that nothing could be done about that, I received an email from the ***** department (Maggie) stating that the case had been resolved. This month I received a message crediting me airtime for 2 cell number's again, I phoned the helpline, I was informed that R2 000 had been credited to the other cell number, which was supposed to be blocked early December, and that my account is R3 800+/_ , I again explained the whole story again, the lady promised me that the problem would be resolved and that escalated debt order would not go off on the 31st of January. I have still not received a reply from the ***** department to inform me what the final debt order amount will be . This is not service customers of 20 years would expect. I don't know what to do, hoping that this review will reach the right person who can help me.
