Unauthorized Billing, *****ed business dealing.

MTN stop billing me for a non service. I have not used your sim card or any service provided by you since my contract with you expired. I never consented to receiving any monthly data from you. Stop it with your *****ed ways and start doing business the right way. I have numerously alerted you that I don't want an upgrade and that you should stop the contract after the expiry of the 24 months. I've been reversing your debits for that reason. I have a thread where I asked your people to cancel, I've also done it over a phone call. Do the right thing and LISTEN!!!!
