Lottery ticket for mistake

I buy 3 lottery ticket for mistake, cost me 15000 of gold. Can i cancel the tickets and take back my gold someway?

There's no support for that. Especially when you do your mistake three times.

Take it as a lesson and double check what you do next time.

15k is not that much, I wish mistakes in life were as cheap as that!

its my first time on lottery system, so when i realize what i did, was too late
