Don't buy from GoSports tickets. They are not based in the uk and as far as I am concerned did not hold to their terms and conditions.
The venue of the football match Chelsea v Crystal palace changed and as we could not then go to the game, I tried to cancel the delivery of the tickets, as in the terms and conditions a deal is considered done once purchase and delivery has occured. Although I was prepared to put the money against my account and use it for another match they said that this was not possible and would also offer no refund.
They were asked before shipping and denied me this.
Furthermore, stupidly I paid 744.72 for 4 tickets which, when delivered were only worth £56 pounds each!
