Happens regularly to me. Consider yourself blessed if they cancel the sale well before the event and the price hasn't moved against you. Bc Stubhub has no qualms about leaving the sale in limbo (won't even let you cancel the sale if you call) for a day or so, as the event approaches, and then cancelling it last min when ticket prices have declined considerably. But if you don't deliver tickets you sold on SH within an ever-changing period of time that Stubhub gives you, expect to be assigned large fines. Funny how that one-way street works, eh?
