We've had the Virgin Media basic TV/landline/broadband package from the get go and had great service with them but as regards to the broadband it's been very patchy lately. It keeps dropping in & out or stopping altogether for minutes to hours at a time.
According to their website they know about the TV problems and are trying to rectify the problems in my area. must be the heat!
I've been doing a broadband speed test everyday for the past few weeks to keep a check, looks OK today.
