I need the travel agency to give me my money back, can I sue them if not? -

I bought a ticket like 5 months ago. My destination was Peru with many stops. In one of the stops I had to saty in Panama for one night (14 hours) when I bought the ticket all the itineraries were like that. There was not warning or any info about having to get a visa for those tickets. yesterday me and my daughter were at the airport when found out that we couldnt flight becasue we didnt have visa to be in panama. I dont know why they put those itineraries when we just want to go to peru. They dont want to refund the money and even a company want to reschedule the flight they coudlnt becsaue it was bought throught an online agency and it was conbine with continental and copa airlines. I am a single mom and I worked so hard to finally buy the tickets and spend the holidays with our family in Peru. I dont have any relatives in here, you can already imagine how we are, I falling into a depression right now but I think i must do something, can somebody help me to have a direction? thank you so much.

I don t think that the travel agency was at fault in this situation. You should have looked up the laws of international travel and found out if you needed a visa for any stop-overs. All you needed to do was to purchase a tourist card that was good for 30 days, for all of $5 or $6 per person.
