Poor service delivery!

Ive finally received my order from Mweb on Tuesday after waiting for a whole month. When I switched it on there was an Internet fault. I called the call centre and spoke to an agent for 2 hours and nothing was fixed. Eventually I was able to connect on my cellphones but not on my PC and Tv. After trying to fix it myself I test my line and the speed is 5.2 upload and download. I ordered a 150 line! Its so difficult to get hold of support and I end up spending more money then I should. Please fix my line or cancel my product im so gatvol right now!
