I can confirm that their customer service is fantastic. I had to hold maybe 15 minutes this time before I spoke to someone but they have always been very helpful and solved every issue I have had. Having said that after confirming the withdrawal address and proceeding with another withdrawal, it still hasn't shown up on the blockchain and over the years every transaction I've made always appeared immediately even though it may have taken taken a while to confirm. I will call them back if it doesn't confirm.
