This is completely unacceptable from an exchange, I know of many other people that have had issues with them and they have behaved in the same way.
Anyone know of any ways that I can reach out to these scammers? Disgusting.
They have a forum account on here that doesn't seem to reply to many people at all, and they also have a twitter handle. Try to PM them on both bitcointalk and twitter nonetheless and keep opening new tickets if they don't answer old ones.
Seems like a lot more people are having trouble with liqui, so it's definitely not just you.
I would recommend getting the hell out of liqui if you were ever paid back.
