Mweb, terrible to no service at all

My internet has been slow now for about 4 to 5 days, I have emailed MWEB, still no reply, I have tried to call them but the waiting time is ridiculous, they say live chat is the way to go but they come on, greet u, say they gonna rest the network, u should check after that, then they stop replying all in all, no resolution, Ano way of getting hold of them, this is pathetic service, and to top of off, a week ago they say the premiums are increasing, so take the money but don't give a good service nor after sales customer service. Time to change service providers
