OK well, I was playing last night a 200 EURO tournament in the only casino on the island... Only one every 3 months
Level Things up 5,000 starting stack, third level at 150/300 and I had doubled up and added some on to 13k and then the CL who had knocked out 7 people in 3 hours, got moved to my direct left and this happens (also spanish only at tables, which makes it harder for me)
Whole Cards...

... UTG, I raise to 900... CL re raises to 3000 (smooth call after everyone gets out the way)
Flop
I check, he pushes in 9000 and I move all in for 1k more. He is very lose and I put him on a strong ace
But then the TD walks in and notices the dealer has not burnt a card...
which makes my set worthless and now only a pair and he is made to burn it and turns over

(now at this point, I kick off not knowing what is going)
Now I ask for my chips back due to the dealer mistake and declare the hand dead... but no, my chips are in and im all in, of course, he has an Ace and i hit the rail...
BUt my question to you guys is
1. Should i get my chips back as the game has changed and has changed the betting structure
2. Am i wrong to flip my cards over on the flop, after i was told im not getting my chips back
3. Am i wrong saying I should be getting my chips back from my all in move, but not my pre flop raise? help im going mad!
