Very lucky indeed. The cause of the issue you experienced might be your internet connection. It happened to me before where I sent one but when I checked the result it didn't send just one but two of it. I open the image you provided and the time is all the same. You also mentioned that you placed bets two times first for 22:10 and second for 22:11. Just contact the stake about it.
The website itself has no liability if we encountered any certain issues regarding internet connections. There's a possibility that your balance will be retrieve if stake.com isn't a scam, because they're uplifting support promtly for their users. However, just wait for the response within the soonest possible time until current issue will be resolved.
The rep of Stake has answered it already on their ANN thread as you can read
here Nothing to resolve, Stake cant do anything in such cases when user's account is compromised. Users are responsible for their own account so users should set the best security of their own account.
