******* service

I have been a subscriber with MTN for almost 30 years. (Same number for 30 years) My contracts have always been close to R1000 a month. This is the first time I have had a small contract - my latest contract I started in December and its supposed to be R209 per month (its data only). I noticed that I am being charged the R209 and then an extra R56.66 on a separate debit order a couple of days before every month so I called the MTN customer service number. A lady there told me that I am supposed to be paying R236 a month and that is why this is happening. She wouldnt understand that the math aint mathing?! R209 + R56.66 is not R236!!! and then told me she is sending me an OTP which I must share with her so she can correct this issue. 3 OTP's later, she keeps telling me the OTP's I am giving her are not valid. I know that I am not supposed to be sharing OTP's with anyone and this whole story sounds really fishy. I told her I dont think I should be giving her this so she info and something is not ok here, so she says I must try another route.

So I am super frustrated, I feel violated, I dont know why I am being **********, I want to know how to fix this and I really think MTN's service consultants should be better trained in how to support their customers. What do I do now? This is really ******* service.
