I have used the app to buy tickets 5-6 times without issue, however I recently did not receive the tickets for my event and only realized at the door of the venue. When I followed up with StubHub the next morning they said there was nothing that could be done since it was after the event. I have filed a claims dispute with my credit card and StubHub has threaded to freeze my account. This lack of customer service is not worth $200, and I'll happily find another way to purchase tickets
