competition unfair - rules changed to stop me winning

Hi Guys, I really really need some advice...

I entered a competition run in England by friends reunited (I am also in England) and I clearly won the comp by the closing date. I got an email to say I was a runner up in the comp and I sent them a message back saying that I had won. They say the end date was 12 hours later than was written above all the photos (I did a screen save so I have evidence). I am now back from my holiday and they have also tried to change the rules (after the comp has closed to favour someone else). Its to win an ipad so I feel really hard done by...I need some advice please. I have screen dumps of the previous rules and also of the end date of the comp along with my winning number of votes and the photo that also won (showing it had fewer)

please help, I am not sure what to do next, thanks, anna

All I can say is move on, we have nothing against the contest organizers.. Some contest are just like that.. I remember when I join a company contest on FB where they announce the winner was the one who has a lesser likes and uglier post than mine. I was so disappointed with the result so I search the winners profile and found out the he was also a member of the company.. Sad right? Don't worry there are still many contest to come since Christmas is coming. A more fair and honest contest, in where they're aiming to give joy to people and not just marketing their product etc..

What the heck?? That's crazy. I see this is an old thread so I'm wondering if anything ever came of this? With all your proof you'd think they wouldn't be able to ignore you.

OMG.
This is too bad!!
Just move on!
