Well, what a giant con this site is.
Here's what happened to me...
I had three tickets to sell, as an issue came up which meant our group of four were unable to attend this gig together. I tried Ebay and was directed to Stubhub. Sorted my registration and listed the tickets at well below the face value, simply to enable a sale to be made. These were listed on Stubhub on Friday 12/07/2013, and, sold on Saturday 13/07/2013. The tickets sold separately as one single ticket and as a pair. On the Monday evening, I was unable to find one of the tickets, and so called Stubhub to inform them. They said that due to more than 48 hours lapsing, I could be liable for "additional fees". I also on the same Tuesday received an email stating that I must send the tickets straight away or face "consequences" and possible charges. The line "you said you'd be able to send these tickets by Friday 12/07/2013" was also in the email, even though I only received the email notifying me the tickets were sold the day after on Saturday afternoon. Why, to who and to where, would I send tickets that I had not yet sold.?
After this, I received another email from Stubhub stating that they were charging my card on file £44, which was the "additional" cost of them sourcing tickets for their buyer. This made the ticket price £90, when in fact, the gig had not even sold out and tickets were still available at Ticketmaster for £60. When I questioned this, I was told that Stubhub would only source tickets from... you guessed it... Stubhub.
This to me appears like a complete stitch-up, as they can then claim the replacement ticket they source cost any amount whatsoever, without anyone really being able to know what the price actually is / was.
This was my first and last experience of this business, I got burnt and will not use them again. I actually called them to "air my views" and told them I'd rather burn any tickets and lose the money than deal with them again.
Stubhub cannot be trusted. Deal with these people at your own risk.
