OK, must profess ignorance... what is HG?
I am so sorry your beautiful Maggie is wrinkled! What a shame! Is that the plum color?
I received a patent bag one time that was completely ruined because the seller folded it into a mailer envelope, and the entire surface looked crushed by the time I got it. It was awful. I've experienced the same thing with plain leather, too! When that happened to me, if the bag was not in remotely acceptable condition, I sent it back (disputed if I had to) and got Ebay to issue a return shipping label for me. In cases where it was fixable or tolerable, I noted it in the seller's feedback (positive or neutral, depending on how they handled my complaint.)
I don't know if it would help you in the future, but after several horridly upsetting incidents, I started sending a note to the seller with my payment to PLEASE ship in a box that fit the purse, not folded or in an envelope, because I'd had several bags ruined in shipment. So far only one seller has ignored that request. That bag arrived ruined and she was a jerk... she earned her negative for that one. :(
