StubHub review: Tickets to a basketball game

I purchased tickets on StubHub and I was to receive a mobile transfer for the tickets. I received an email at the time of purchase stating that I would receive the tickets sometime the following day. I received an email indicating the tickets had been transferred to me but never received an actual email where I could accept my tickets. I got busy with work and activities. By the time I called in, it was after business hours. I called the night before the event and the morning of the event but it was after their business hours. I had to purchase alternate tickets through a different company to ensure we were able to attend the event. My party was already in route to the event by the time STUBHUB was open to take my call. They admitted that there is a glitch in their system that the emails to accept the tickets sometimes does not arrive or never gets sent. Then they lectured me that I should have called in sooner. When I explained that I did and the situation was complicated by my living in a different time zone they said they could not help me because I did not call in sooner. If they know they sometimes have issues with buyers receiving their tickets then they need to provide 24 hour support to resolve such issues or do the correct thing and offer a refund.
