Mtn

I really don't understand MTN. I took an upgrade beginning of May 2024 for R381 p.m. And insurance for R129. So they tell me they will start debiting end of June 2024. I voluntarily decided to pay R381 at end of May to avoid double debit. Now I wait for them to debitbmy account end of June for total of R511 or something around there. They only debit R129.55 and suspend my service. When i call, the first consultant says it must have been something wrong with the collections department. The second consultant says the R129.55 was for something else I must still pay R500 . I explained to him that R129.55 Is for insurance and why are they not debiting for the contractvof the device. He says I must wait. I ask him to check how much exactly should I pay or in arrears for, he then keeps quite till the line drops. Can someone who knows what's happening with my account call me to explain.
