They wouldn't refund me within the time limit, so I bought another ticket.

You should not buy a combo with a lunch box because there are only 1-2 trips/day of this type of bus that stops at the village. I had to give up 2 meals because there was no suitable trip. You should swipe your easy card to go each leg, there will be more stations and options. You won't have to worry about not having a ticket.
