Hi There, I am having the same issue here with them chasing £280 because i cancelled early. I have recently moved address and around the same time got a new phone contract which issued a new telephone number. I have been reciving letters because we had a postal re-direct but this only runs until April. Basically they have no contact telephone number or address. My question is, will these people be able to find out any new details on where i live etc? Do they have the power to do this? Thanks in advance for your input
