MWEB VOIP phone complaints falling on deaf ears for 34 days!

I have logged 10 tickets and spoken to 7 different "expert technicians" since 18 October and still my VOIP phone is not working. each technician promises me the "expert" will phone back. One admitted to me the fault is on MWEB server. yet no one can fix it. I cannot make or receive calls on my VOIP phone. I reported it to the manager 20 days ago and still no reply to my email!!!! when i ask they must send a technician to figure out what is going on they calmly tell me they don't send out technicians!!! when i buy a product and a service i expect that MWEB give me the support to use that service. not just take my money every month without resolving technical issues. Anyone here knows the ICASA complaints commission contact details? I'm so fed up.
