When your ping is too high, toribash will just disconnect you from the server. A high ping doesn't mean that you immediately lag alot, because in toribash you got alot of turns instead of a smooth ongoing gameplay like normal games. Neither does it mean your internet is very slow, it's just the reaction time of your internet going bad for a while, something like that, you can search for the exact description of ping on google.
Nobody will refund you, as it sure as hell isn't toribash's fault.
