MTN ****ming customers

If there was something less than 0 I’d be giving MTN that rating. Is there any brach beside ombudsman that help those victimised by networks. MTN is currently deducting money on my account that I for device that I did not take. They also charge me cancellation that I don’t even understand what is it for. When they explain they say it’s device fee but I never had their device these ******. I think we all need to gather together as South Africans and leave this stupid network.
