My box is saying loss of signal i suspect its the cable going from the dish into the box as it pulled apart, I put it back toghter but nothing

it was flickering for a few days and flckered more when you went near the cable.
I'm actual wired for Sky and Virgin cable ( well Virgin sits unused not plugged in as i dropped the service) if they are going to charge I may as well just jump back to Virgin as I'm thinking about going back to there BB later in the year over Be BB through the phone that only gets me 8mb.
So do they charge? I remeber somone saying £70 and thinking well if it goes down I'm not paying if they want me to be a customer.

Just to add they do want £65 so I guess I'm going to cancel it as i had car cost this month and cant afford a hit of even £65.
