I have been using Kraken for a long time and I have never had a problem. I have withdrawn USD multiple times and received my funds in a day or two. However, the last couple of days I have been trying to withdraw USD and each time the transaction is failed with a couple of minutes. No explanation or reason given. I get the email saying a withdrawal was requested but the transaction has actually failed. I am tier 3 verified and I have the funds to withdraw. Like I said, I made a withdrawal in April and received my funds in 2 days.
I submitted a ticket and I am awaiting a response. It appears I am not alone with this problem but anyone who had the problem resolved if you could post what went wrong, maybe it will help be resolve before support gets back to me - I have no idea how long that will take.
If support doesn't get back to you soon, you can use this form to escalate the ticket:
