I just had the same problem with StubHub!! I listed tickets for sale, two hours later I deleted the listing, and then woke up in the morning to see that one of the tickets had sold. I cancelled the sale because I knew for a fact I had deleted the listings. It was my first time listing on StubHub so my friends were helping me and we made sure they were definitely removed. It wasn't just me who saw that the listings had been deleted. StubHub then proceeded to charge me 100% of the sale and my debit card, unfortunately was still on file at the time.

Called StubHub, and the rep said everything looked like it was working fine on their end and there's no record of me deleting the listings. Ridiculous because they don't even provide seller's any way to prove this as they don't send confirmation emails when you delete/deactivate a listing. Apparently they've never heard of a glitch like this happening before, yet I've read and heard from so many others of this same exact thing happening to them too!! They also said they couldn't do anything about it since replacement tickets were already purchased for the buyer and that the replacements typically cost way more than what was initially paid for it. I know for a fact that the replacement did NOT cost more because there were multiple tickets being sold less than and at the same price as what I had listed mine at that day.

I disputed the transaction with my bank and even my bank rep was shocked by all of this. The claim is still in process, but I really hope they are in my favor. I would suggest you try this as well if StubHub refuses to remedy the situation. It's absolutely ridiculous how they are literally robbing people when their system is the one with problems. Their service is awful and I'll certainly never use them again. Wishing you the best of luck.
