I'm sure many of you have had similar things... I get home from work and have a letter addressed to the occupier, I roll my eyes wondering what rubbish this is going to be. Only to discover this is worse than the usual junk mail received, this one is from EON and claiming I owe them a £136. The bill is based on estimated usage and covers the few weeks I lived in my new house before changing to my current provider. I was never aware EON were providing gas to my house and if they were I'm not sure where the electric was coming from, as the bill for that on the same letter is £0.00. Should I pay this money, despite the fact the bill is based on estimated usage, is for way back in November - December 2013 and they don't even know my name? I'm not one to avoid paying for what I've used, but it feels a little unjust and being estimated, I don't quite understand how they can be asking for any money?
