Chase from Kraken support here. I'm very sorry to hear about this and that you feel the support team has been unhelpful. Security is our top priority and this is the last thing we'd ever want to hear from any of our clients.

For the highest level of account security, it is absolutely essential that users fully utilize the various security features that the Kraken platform has to offer (not just login 2FA, but funding/trading 2FA, as well as a Master Key and Global Settings Lock). More detailed information outlining the various available security features can be found here: https://support.kraken.com/hc/en-us/articles/201396837

If your support request is still outstanding, please provide us with your ticket number so we can further help and work with you in regards to your case. Please understand, however, that for security and compliance reasons, we are unable to provide further information about individual cases until we are contacted by a verified law enforcement official.
