3 weeks ago we started having a bunch of problems with our Smart Hub, Broadband TV (HD Channels, Sports Channels and other Subscription Channels) and our Internet Connection, our Smart Hub wouldn't connect to the internet and have a constant flashing purple light. Now the Smart Hub seems to be fine (been up for 3 days without going down) we get the Sports Channels and Subscription Channels, however the HD channels (BBC 1 HD etc) constantly stutters and pixelates then ultimately freezes, and our internet speeds are probably slower than the dial up days. Now we have ran every diagnostic in the book, been on to CS more times than i can count, been given 3 seperate engineer call out appointments and has only shown up once and when he did, he told us the problem was with the box or exchange and that he would need to get an "expert" team to fix it as he couldn't and we would be contacted, we have yet to be contacted (this was 2 weeks ago). On Sunday there i was on the phone to CS and they finally acknowledged after telling them a million times that we were having a problem with our internet and the line. He said they would monitor our line to the exchange and we would be contacted by the network team in 24-48 hours. Well it's now over 72 hours later and no phone call.
It's an absolute shambles and i'm honestly out of ideas, no point in phoning CS as they will tell me what they have for the past 3 weeks, so you here is my only hope.
ETA: 40mbps Down / 10mbps Up was the internet speed we got after BT Infinity was installed.
