I'm having some serious problems too.

My order hasn't been filled and I haven't heard anything back from my ticket I submitted.

I used to really like bitinstant, but I'm starting to change my mind.

I've also got a horrible feeling that they're going to pick the highest price they can to sell me my bitcoins. I ordered at ~$140, not $200.

Bitinstant support, this is your chance to make things right and not sell me overpriced coins.

Your move
