I believe that all samsonite bags are under warranty so they should repair it for you at a samsonite store or you should call their customer service number.
If your luggage has any manufacturing defects in the material or workmanship, Samsonite will replace it or fix it if the damage is small. Hope this helps!
You close your bag just like any other bag. Please refrase your question in a proper way so we can know better how to answer your query. I am a big fan of Samsonite bags, especially Samsonite...
