Unfortunately, we can't cancel a sale after it's been processed. Ticketmaster Verified tickets are reissued into the buyers name after they sell and this process cannot be reversed.
If you sold tickets as PDF/Electronic Delivery and you are unable to provide tickets as sold to your buyer, you won't be paid and be charged admin and associated replacement fees. More information is in the Seller Agreement you read and agree to prior to listing. If you can't provide the tickets as sold, you should let us know as soon as possible by submitting a request.
