Gobank Gobank "lost" money from account Internet

Gobank had a glitch in their system and took $300 from me and are not responding or returning the money. I was paid on Wednesday of this past week, when my paycheck was deposited, I moved an amount to the "vault" which is their equivalent of a savings account. When I did this, the money disappeared. I contacted go bank, and offered proof of everything and was told they would take 24 hours and review my account. I had not heard anything after 24 hours so I called again. I was told that my employer must have reversed my paycheck and that's why my $300 was gone. I called my employer and they denied this, it also clearly says on my account ledger that $300 was moved to the vault, it was just never credited. I am now at 72 hours and have not heard back and am no longer getting responses to my messages or calls. I am furious as $300 is a very large amount for them just to take out of someone's account with no explanation. It CLEARLY shows where the money was moved and not credited.
