Sorry to hear that, apart from contacting them directly I'm not sure what else can be done. I assume you've tried the message form in the FAQ? Also just a slight thing, you say you've emailed
[email protected] , the website is freebitco.in, so did your emails get bounced back or just not answered?
Freebitco.in is primarily a gambling site, and the site hasn't changed much, if at all, in many years; I highly doubt they have a large support team so any replies will probably take a bit of time.
For me, I see Freebitco.in as a free lottery. I've never bought fun tokens; just collected the free satoshis, exchanged RP for extra satoshis, and then withdrew those satoshis when I hit the minimum payout. You need an old style withdrawal address starting with 1 ... The site works and keeps gamblers gambling, they use lots of little tricks to make you feel really good about gambling; but the odds are always in the sites favour (on the multiply game, it shows you the odds you are getting; a 50/50 chance, wager 1 sat win 1 sat, you only have a 47.5% chance; the house always wins) - so why would they ever change the code if they didn't have to, or keep a support team around to dive into code that's been running for years?
Not your keys, not your coins, applies here. You and I have no control, and any resolution is going to come from getting in touch with them. I'd say be patient and wait for a reply, keep the screenshots safe, wait a week get in touch with them, be patient and wait...
I wish you the best of luck in getting this resolved.
