StubHub review: Purchased tickets for carrie underwood concert that was cancelled 1

I purchased tickets for the Carrie Underwood Concert to be held on September 20th at Resort World in Las Vegas, NV. On the day of concert (9/20), I checked my tickets to ensure everything was signed, sealed and delivered. There was a notification on the mobile ticket which indicated the concert had been postponed. I then drove to Resort World and spoke with two staff employees who stated the concert on that day had been cancelled. I then called StubHub to request a refund of my tickets and was told I would need to wait until I received notification that the concert had been cancelled on the StubHub sight before I would qualify for a refund. I waited until 9/27 (a week after the concert) to re-call StubHub to request my refund. I recorded this session as I wanted to ensure there wasn't anything that could be said on either end to indicate fraud. I spoke with a representative by the name of Amelia who would not give me any additional information as to employee number or branch...she put my on hold twice and finally came back to tell me that I would need to wait for an email from StubHub saying the show had been cancelled and I would need to do an additional act in order to receive my refund. When pressed about the fact that I had already requested a refund a number of times, she promptly told me I would need to wait for the email and then hung-up on me. And...I might add, throughout the phone conversation, Amelia continued to repeat the phrase "No problem", which I feel is ludicrous, as there is a BIG PROBLEM with me receiving my refund!
