I purcahsed the Gucci Boston Treasure Bag in April with receipt from Ebay. There was a stain but since I was going out of town and purchased the bag for that purpose, the seller agreed that lowering the price would suffice. I wore the bag three times, the third time the handle broke. I took it to the Gucci Boutique and after a month I was told that the bag wasn't authentic. I've made several attempts to contact the seller to no avail any suggestions?
