LADY GAGA TICKETS WANTED PLEASE Tel ?

I bought 8 tickets to see Lady Gaga in Manchester and the guy who sold them to me has done a runner, with the money. We have some very upset young ladies who I am now trying to get other tickets for. We have transport and hotels paid for in Manchester and desperately need some tickets. If you can help please get in touch. I will buy them. Thank you for any help you can give.
