When I placed the order the exchange rate was at just about $103. Paid with Dwolla, who approved the transaction, but at the end of the bitinstant transfer log there was a MTGox communication error message. Contacted support and was told that the bitinstance account balance at MTGox was temporarely low, and that the transfer would go through when the issue was resolved. I waited 24 hours and contacted support again, at which point I was told that the the transfer would be initiated manually (last message in the order status now says "Manual transfer created"). Sounded like everything was well until the funds showed up in my wallet. It looks like the transfer was done at the exchange rate when the manual transfer was initiated. That means I ended up getting 0.1 less BTC than what I had paid for. Contacted suport again about 24 hours ago, but never got a response.
Do you have an order ID #?
