Slush pool 2fa locked me out

[superbtc4376]

Hi guys

I was in the process of setting up the 2fa on Slush Pool and it wasn't working. Unfortunately the site said it did and now there is an one time password which i don't remember setting, and a device capabale of a 2fa passcode. There are no registered devices! I can't disable it! What do I do?? I need to change my wallet address.

Also my mobile slush app works.

Is there customer support?

I'm hoping to trick it with a yubico security key if possible
