Hmmmm so whats going on here then?
As said I am pre payment meters so they dont have any bank details and no way to pay me the £50?.

I've had a read, looks legit and guess it makes sense. With pre-pay you have to take a key to a shop and then they put credit on right? In that case, it's not like post-pay where they can just credit your account. I know it's already been said but if you ever are in a position to move to post-pay you'd save a fortune with your kind of usage.
