In June 2019, I booked a trip with an agency Rainforest Cruises for a boat trip in Brazil. I had to pay the balance on 18/4/20 even though we believed we wouldn't be able to travel due to Covid 19. We couldn't travel internationally due to Government rules. The company wouldn't refund the trip, and we had no option but to take a credit note. We later discovered that the actual boat trip was subsequently cancelled. The agency are insisting we must make a booking with the credit note by 30th March 2021 for travel up to July 31 2022, otherwise we lose the credit note of nearly $2000. International borders are still shut, Covid is still very uncertain, and no travel insurance is available if we book now and have to cancel again due to Government rules. We don't feel it is reasonable to have to book by March 2021 in light of all the ongoing uncertainty and we can't predict that international travel to South America will be ok even next year. I know nothing about USA consumer law, and would really appreciate advice about whether we can get a refund to replace the credit note, or whether we can insist on a more reasonable extension for a trip in 2023.
