I hope you are right about getting my money back. I can't remember having such a bad purchase experience apart from 2 years ago when I ordered a Macbook Pro from a reputable company and received 2 bottles of apple cider and some old chargers instead... the tape was sliced open at the bottom of the parcel and another layer of tape was carefully put over it... I got a new shipment with a better delivery service a few days later and the actual computer. But I spent a whole day worrying, phoning the seller, my bank and even police. I understand the seller needed to assess the situation and rule out that I was trying to scam them. I didn't film the opening back then as nothing bad ever happened... I learnt to film high ticket purchases since then, just in case. And learnt from the police that scammers apply to delivery companies just to steal contents out of parcels (the box had the company logo plastered all over, a known electronics company, and the shipment was initially scheduled to arrive on a Friday, but then I got a message that I wasn't at home - not true - and they would try again on Monday, effectively giving the scammer/s plenty of time on the weekend to pull this off).
I'm used to paying taxes for everything from outside Europe and always calculate with 30% on top of the total price. I still got good deals on a vintage Barenia Evelyne and Chanel Classic Flap. Or some downright bargains on vintage LV pieces. I like how detailed the pictures and descriptions are from great sellers. Usually makes the items turn out to be better than expected and make me want to purchase again. Win-win. I'd love to see a new company do what Vestiaire does, but with consistent and high standards. Not even accepting sub par photo quality.
I think you may have a resolution on their end. The CC company probably started proceedings on their side as well.
I feel that delivery companies have become increasingly scammy themselves, due to bad eggs entering the teams. My packages arrive routinely ripped open (the latest DHL one had been thoroughly opened and badly repacked, but the contents were fine as they didn't recognize the value of them).
A number of packages have also vanished with a note saying that they had been "delivered to the front desk" (our building doesn't have one), "given to my 8th floor neighbour" (we have 6 floors), and left in secure location outside the building (we are on a busy street, so anything left outside the building is gone in 60 seconds, removed as trash or picked up by someone). Not that they gained much, what went missing were a couple of door stoppers, a frame for the trash can and a handful of spare parts.
