Ticket Cancelled

I bought 3 tickets on line with ticketpro. I paid for all 3 but I got one sent to me, I queried this with them sent an email saying they either give me the outstanding 2 tickets or they must refund me. Agnetha said she'll sort it out which she did as she sent me the 2 outstanding tickets. What irritates me the most is that ticketpro cancelled the first ticket that I received initially and NEVER informed me. I'm beyond furious because I only noticed this when I got to the stadium. Why didn't ticketpro inform me of the cancellation I don't know. This is best service at its best
