What transactions are you suggesting they try to suspend? You can't call "backsies" once you've sent your Bitcoin transaction. Once there's 1 confirmation on the Blockchain, it's in the history books.
That's the beauty of Bitcoin. No chargebacks or pending authorization by institutions or card companies.
The whole issue was with their automated order system pairing with Blockchain. Once Blockchain had issues, they had to manually process each order submitted to them.
Let's see you try to enter a few hundred orders of different quantities at 4 decimals places and ship each unit correctly throughout the world in a matter of hours.
What i meant was once they saw they were having issues they should have put a hold on the ability for someone to order, so that they dont have to spend time confirming more transactions that pile up.
