False advertising!! They can’t give a 200/100mbps line

If I can give them a 0 star rating, I certainly would!!! Home-Connect is bull****ting the public!!! I ordered a 200/100 mbps which they installed together with the router that they supp****. Since installation (almost 3 weeks back) the fastest download speed we had was 140 mbps. After numerous phone calls to them trying to get the problem resolved, Happy from Home-Connect today said to me that they recommend that I downgrade to a 100/50mbps line, as the routers they have can’t handle the speeds. How ridiculous!!! Can someone from Home-Connect management please call me, as I want this line cancelled immediately. But firstly send me a email stating what Happy has said - that Home-Connect can’t help me with a 200/100mbps line as per my contract with them.
