Bt guarantee broadband in every room. Funny that, they could not fix our broadband after 7 visits and we never received a proper service at any point throughout our contract. They claimed my wife couldn’t set up her phone WiFi, and offered to help her. It turned out they could not do their job. Don’t bother with Bt they are not bothered in helping customers. Utility warehouse now prove a service is possible and it actually works properly..
BT don’t bother yourselves.
