I wish I could help you but they owe me money too and have flatly refused to pay it back. I suggest that you report them as a scam to various websites where they do business. If they see that angry customers are preventing them from raising money for their ICO, they might decide that it is in their interest to pay us back. These are sites where you can report them for abuse:

ICO Bench, a major aggregator of ICO information. Click the "report" button on the right side of the page: https://icobench.com/ico/bitxoxo
LinkedIn: Click the "..." next to their name: https://www.linkedin.com/company/bitxoxo/
Twitter: Report them for abuse on Twitter by clicking the "..." next to their profile
YouTube: Report this video as a scam by clicking on the "..." button: https://www.youtube.com/watch?v=FXstfTbucOc
Medium: https://medium.com/@bitxoxobitcoin (report abuse by clicking the downward arrow next to the "follow" button)

I'm also working on contacting their bank and contacting legal authorities. If you have any suggestions for what else to do let me know.
