Disappointed with vumatel and mweb

Our area recently installed Fibre and we being new tenants in the area got vumatel to install the modem which is on but no signal and Fibre via mweb. We called through immediately on the same day and mweb notified us that vumatel didn't plice the cabling properly so we can't access anything. My point is why would they sell a product with UPFRONT PAYMENT when it was not done properly. Here we are siting with the problem but can't seem to get help from either of the companies. All they say the problem has been escalated. It's been over a week and nothing has been they have taken our money but BS services... And we have made numerous calls regarding this. With no effort in return. Disgusted with they way they do things.
