If you listed and sold tickets that are only on Will Call pickup, my apologies but the sale would need to be canceled. We do not allow Will Call as a delivery method as there is no way to 100% confirm the tickets are there or that the buyer picked them up.
Sellers do need to ensure that when they list their tickets that they are able to fulfill using the method they have chosen. If not, the order would be canceled with charges being placed as the tickets were guaranteed to the buyer.
I'm really sorry for any inconvenience with this. I'll send you a private message to see how we can help though and potentially keep the sale.
Other sellers with a similar issue are welcome to send a private message to any of our moderators.
