Mtn is commiting *****ulent activities on our accounts

Mtn is ****ming us of monies. I had network issues half of August one agent said there is no tower near me hence no network but I have been using their router for months without problems in this area. Once the network issue gets fixed after I fought with them several times I find out I am owing 1200 only to find out one of their agents added usage on my uncapped data I wonder how that is possible. I keep on receiving my query has been opened 3 to 4 times everyday. It keeps on sending messages I have been repovisioned my order has been opened 3 to 4 times everyday. Which order is this? I believe adding a product to one's account without their knowledge is *****. How is it that I owe 340 ontop of my monthly 845. I need that debt removed and that agent investigated how many more South Africans are being ****med by mtn on such things. I will not o ay the 340 I don't know wat is for. I have an uncapped data so I don't Believe anything can be added on that. Mtn your service delivery is poor and I am sick n tired of such service while I sm a paying customer fix it.
