Thank you!Just take your bag to a Prada store or department store that carries Prada. If you purchased the be less than a year ago the repair will probably be free. If you go to Prada you will need the authenticity card unless you purchased the bag from that store and they can look it up in their computer system.
I was told mine had a 5 year warranty when purchased last week...and that it can go back to any Prada store in the world
