So what do you do, and how long have you been waiting?
I had many delayed withdrawals before, but after they were processed I could always find the transaction at blockchain so I knew they were sent. Now with no transaction they seem like they have disappeared.
Not showing up on blockchain for me either, keep emailing them. If I don't get it back I have a coworker who does seo and only thing I can do is make sure everyone knows bter steals bitcoins.
