Trust me, nobody manually handles your bets. You placed your bets with a computer and unless you copied the confirmation ticket number, I doubt they can do anything about it.
If you, in fact, got a confirmation, they will be able to track it and find out what happened.
Did you have other bets that were all placed at the same time? Were these bets you are talking about placed all at the same time? Could you send me the time you placed the bets, it might help them track them.
You talked to a minimum wage night shift clerk that probably isn't allowed to make phone calls. I guarantee you will hear from somebody today.
I have emailed my contacts there and I will probably hear back from them late morning, early afternoon.
I'll find out what happened.
