Cable Forum - Internet service become useless

I've been with Virgin for years without any problems but recently it's unusable for streaming! Youtube, Netflix etc. I'm on a 100 megs service and only get 40 megs. there's been a fault in the area for some time. it was supposed to have been fixed but its happening again. There was a crack in the pavement out side of the property this was removed and new tarmac was installed I wonder if the BB cable is under the new tarmac and could it have been damaged when it was done

I've run a test with the virgin tool to test and saying there is a fault in my area the same as before!!!
