MTN POOR AFTER SALES SERVICE

My neighbour and I app**** and MTN installed airfibre last month. Our installations took less then 2 days. Today my neighbour and I experienced very slow internet access. Two hours later we completely lost connectivity and No Internet is displayed on our devices. We logged a ticket through a Whatsapp Business and text to firstline support. I then received a Reference number: Ticket: SST*** So, after sales support is 3 - 9 days before MTN airfibre respond. This is POOR AFTER SALES SERVICE. I work from home, will MTN pay for the days I CANNOT WORK??? NO INTERNET FOR AT LEAST 3 DAYS, IS DISGUSTING!!!!!
