Thanks, that's much better. I'm using tools on the internet, notably Google and not something special.
We now have an address to work with, albeit a PO Box and not a physical address.
My suspicions are that this promotion is run by a third party that specialises in this sort of thing, so it would be pointless ringing LG or Sky directly.
As it's a PO Box, let's see what other promotions use it. Put the PO Box and postal district of the postcode into Google:
"po box 7629" "ng18"The results reveal that it has (or is) used for other promotions as well as this Sky/LG one. The
Littlest Pet Shop (part of Hasbro) has a promotion which uses it. Also WWE Royal Rumble 2009.
We need to find the name of this company.
