Is this collusion? (Party $11)

[wulfheir]

I'm at work and don't have the HH on me.

$11 eurobet
5 or 6 handed. I'm short stack.

I go all-in UTG, UTG+1 asks what everyone has, 3 players in total type their hole cards. UTG+1 calls, everyone else folds.

I emailed support and they replied saying that UTG+1 had every intention of calling my all-in before the conversation (how does CS know this?). Also, he told the table he had TT, but really showed 77. Support told me that they weren't even giving their real hole cards so there can't refund my fee, but will ask the other players to wait until the hand is over to discuss it.

Would you pursue this further or let it be?

edit: spelled 'persue'
