BE WARNED - SERVICE IS TERRIBLE!!
I am just adding to what all the other frustrated customers have already said...
It is impossible to get customer service. In my opinion, there is no consideration for the clients time and the only interest of Virgin Media is to cut their costs. When you sign up you will be fooled by the prompt service because of course new sales is all they are interested in.
Be warned... If you ever need support it is going to cost you dearly.
I could never recommend these guys to anyone.
