its all about holding your nerve
plus only listen to offers from the cancellation department!
when our standard sky plus box broke i rang up and asked for repair and they said it would cost £80!
after some umming and erring they halfed that to £40
but i insisted i wouldnt pay and told them to put me through to cancellations!
i insisted due to them trying to charge for repairs i was going to leave and got a free sky plus box and a free install, but the guy just happend to mention alot of people were leaving due to the credit crunch muhaha i kept pushing and got a free month an £5 knocked off every month.
