My mum is currently looking to change to sky broadband and talk, we have phoned up sky, the order has been placed but they are saying that the mac code we were given from her previous internet provider " post office " wont register on their system and is wrong. We were told to phone post office and tell them it wont work and they should give us a new mac code, however they have said the mac is deffinately correct and not expired so untill it expires they wont give us a new one ... is this correct or should they give us a new one now because clearly it isnt working? sky said they arent allowed to say they wont do it because I did querey that with them.
