It seems your agent has printed out the receipts against a reservation system (like amadeus, galileo, etc.) which is typical for agents.
They should have also provided you with a link where you can view your itinerary - something like a link to viewtrip.com which is Galileo's customer facing portal; or checkmytrip.com the equivalent for Amadeus.
In both of these places, or on the paper reservation - you should have your PNR number.
You can use this at the airline's website to retrieve your booking and your e-ticket receipt.
At the bottom of the e-ticket receipt, you should see the terms and carriage contract and any specific restrictions on your ticket class/type.
Most airlines have their contract of carriage available online (for example, here is the page from united which also links to the terms for their partner airlines), you can also research there.
However, I am confident that at your e-ticket receipt you should see the correct applicable terms for that ticket/fare class, etc.
