I pretty much agree with Roey...and further, my take on this would be i would definitely try to return it, but would tell them what happened. If the truth is told in earnest and nicely, sometimes the SAs (or department manager) end up doing all they can to help you -- not always, but it does happen .....for the prices we pay for these bags...to me, its outrageous for anything to happen
within the first year (unless we are being careless or bag has been tossed around alot).
I have done that and the SA says "i am so sorry, of course we will exchange it" you owe it to yourself to try and just tell them sweetly "This is what happened to my bag, and I am shocked that a bag of such good quality had this happen to it, even if i used it a few times. Do you think you could allow me to exchange it?"
let us know what happens
