Disgusting customer service

I have been using MTN for the past 20 years. All l can say is how f***Ken feed up l am.The service levels had deteriorated and nobody cares.l have been trying to cancel my wifi router contract for the past four months, but invain which means l have been paying this company money for a router that they have failed to make me connected to.l have made countless phone calls gone to their big branch in Mall of Africa for more than 6 times and no one seems to know how to help or even show interest. Their service is disappointing and you can sense from the stuff deminure that there is no accountability whatsoever .They have changed me for months for a connection that they have failed to fix.l guess charging the poor customer so they become even richer is their moto.l was promised a call back from MTN Mall of Africa a week ago from Noma and am still waiting. For anyone who needs a home router please please try your luck with other service providers not MTN .You will regret it
