Poor service

The Vumatel installed the fibre box, and Mweb is the service provider. The box is connected but there's no Internet. I have been contacting them since Monday after they installed the box. When I call Vumatel they refer me to the service provider of which is Mweb. I feel ****med as they are failing to fix the problem and it pains me that I am using my airtime to contact them and no one contact me to give me feed back nor progress. I want them to come remove their box and refund my money. Their service suck and I am very disappointed in them with their empty promises. I am unable to use something I already paid for hence they will expect to take money again by the 15th. Vumatel and Mweb are a disappointment in me, they failed me
