Vumatel and webafrica bad service

For the past 7 days I'm trying to have my service working 100%. On Sunday last week I contacted webafrica and vumatel they assured me that it will get sorted 7 days later I'm still struggling with no Internet connection. Technicians came out changed my router but yo no avail. Contacted webafrica over and over again from level 2 went to level 3 now sitting at level 4 this means nothing to me. Now I cannot get intouch with webafrica on their whatsup chat line for the past 2 day and vumatel is telling me it's not their problem. Unacceptable from both organisations and very unprofessional. I pay for a working service not spending more on airtime that i have to purchase to get my service up and running. They don't even have the acument to pick up a phone and call you back it's all on the client. So what do i do from here
