NO resolution on queries and NO internet!

I recently became a customer of WirUlink and have not been happy with their service at all. My father has a secondary router (which he obtained from WIRUlink) and wanted to rather obtain his connection from my router. They came to do this and instead installed another point in my room! They were questioned about it and then moved over to his router and did some work there. It was never tested. Since this installation he has been unable to connect to the internet, unless another wire is connected. I logged calls for assistance, but instead of offering assistance we are told that it is common for slow connections, so slow that he cannot even open whatsapp! He was asked to download an app, which he cannot even do, as there is no internet. He then checked some cables and all of a sudden had internet. Only to find out, this is because his connection is still to that of another main router. The one we asked him to be removed from.

I have now logged another call for this to be resolved. But I am extremely unhappy that we pay for services that are not delivered. Complain and instead of offering assistance they say that it is normal. If I had known that their service was this horrible I would have stayed with my previous provider! But sadly now I have signed a contract with them and I see other complaints about the ridiculous cancellation fees.
