MTN NO DATA COVERAGE

I took out a Data only contract one year ago for 24 months.This contract is for my security as I use it to access my CCTV cameras at home when I am at work, and for the past week I have no coverage due to a MTN SITE that is not working properly.I have tested my router by bringing it to my business premises with the sim card in and it works fine ,when I plug it in at home it has no internet access.I reported the matter to the coverage department and still not resolved and I am not the only client in the area with the same problem. MTN has no urgency where it comes to things like this,they take your money every month but cant provide a service.JUST AS I AM HELD LIABLE FOR THE CONTRACT TERMS TO PAY SO ARE THEY TO PROVIDE A SERVICE FOR WHAT I AM PAYING FOR. MTN is putting my security at risk and if they cant resolve the problem they must cancel my contract.MY NEXT STEP IS THE CONSUMER PROTECTION BOARD. Clients are just letting them get away with to much. Welkom(Free State) Doorn (Welkom
