sky is not good

i do not like sky! it was working fine for the first 7 years i had no problems what so ever with it. Well that was until now! my sky box isn't working it says no signal all the time and i am paying lots of money for it !!!! so people i just want to tell you don't go with sky. when i call them up they just put you on hold for ages ans it is so annoying i just want to tell you this so you don't have to go through what i did :) but there sky hub is OK but it is very slow
