Very very very slow internet

Why does my internet go on/off every 5 minutes? How am i supposed to work from home? Why can't I even get through to your call centre to lodge a complaint or report on the matter? Is this what i pay for every month? Are you actually proud to offer a service that goes on/off every 5 minutes? Is the reason for the high call volumes in your call centre because all your customers want to complain about the bad service? Why are you always experiencing technical difficulties on your main platform? What reason do I have to continue using your service every month? Shame on you Telkom!
