Sorry jannette i think they take the box back... because in the contract you signed when you got the stb (set top box) it has a clause if you dont continue with the service they will come and collect it....
But a little good news for you... My mate was stoped his £34 amonth deal with them and did not want to pay for it at all they said that they would pick it up every time a courier called he did not answer --- on D phoned him and asked why he never gave the box he said he was out and they sent some more couriers to him and he never answered.... and on d have never bothered him since and that was in jan this year
