I entered a competition?

[Amelia]

I am a massive fan of TOWIE- like huge!
And TOWIE is sponsored by 'Casio Sheen UK' watches.

On the Sheen UK facebook page there was a competition to win one of their watches SIGNED by 2 of the TOWIE members- plus a pair of Babyliss hair straighteners worth £80.

I entered like many others and I was the one that won! (really happy)

They told me to message their page with my postal address and so I did, it has now been about a week and I still haven't received it?
How long do you think it will be? I was hoping it would be at least ready for Christmas as it was a Christmas prize..

This is their page ----> https://www.facebook.com/UKSheen?fref=ts

And this is the picture from the page where I saw the competition (which I have commented on, plus you can see their reply to say i won) --------> https://www.facebook.com/photo.php?fbid=...=1&theater

I am mainly worried it's not legit? I don't know?
