MWEB POOR CUSTOMER SERVICE. CANNOT GET THROUGH TO A TECHNICIAN

I have tried to call Mweb Technical support several times. No one answers and the amount of airtime I have wasted is ridiculous. My mother paid for 150/15mbps, however whenever I run speed tests we are receiving around 50/50mbps. My mother has passed on recently and I was in the process of changing the account ownership. Before I do that, I would like to speak to a technician about our speed problem or have one come out but I cannot get through to anyone. Their live chat is also hopeless. At this point I'm considering cancelling the account.
