Mtn ostrich approach to their poor network service

Mtn refuses to acknowledge complaints sent to numbers we were told to use ! For years we have told mtn that there is a problem and they have pretty much told us well there nothing they will do . This month alone we have have had hardly any coverage and messages , messengers calls you name it and we are not even acknowledged . It’s like mtn system has crashed completely and instead of taking responsibility they have gone ostrich ! It’s disgusting service mtn! You claim to be Africa no1 network so proof it cause you sure a hell are not at all !
