This sucks lol. I was one of the tuesday afternoon orders. The worst part is, this is my first ever attempt buying bitcoins and I dont even have a bitinstant account. I did this as a guest, so I have no way of checking the progress of my order. Im freakinggggggggg out lol. I contacted zip-zap and they said they can refund my order tomorrow if I still havent gotten my bitcoins. So that put me at ease a bit.
Go here:
https://www.cashpayment.com/Public/CheckMyPayment then enter your zipzap account number if it says "Paid" then they are ""Supposedly"" working on getting it processed. Although don't hold your breath, still haven't seen one single person from Tuesday get their zipzap order finalized as of yet.
