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 fixed.
