How much would it be for me to have NTL installed in my house? I'm currently on SKY but I'm getting P***ED of with them wanting £82 per month, I have a SKY box downstairs and one upstairs in the bedroom, they are trying to bill me twice because the box downstairs is not doing a call back, a engineer has been out 5 times over the last year, the latest one decided to change the box, all was well up until a few weeks ago when it failed to do a call back, Ive received a bill this morning for £82, thats the full price for 2 boxes where as I only pay £51 per month.
