Tried to purchase Coldplay tickets through Ticketmaster's web site during presale... chose seats, went to pay for them, and received message "Sorry, we cannot complete this transaction at this time." End result: tickets disappeared. Tried again... same result. Tried a third time... same message. A week later, during regular ticket sale, SAME THING! Contacted customer support... got a "canned" email apology with an 800 number for assistance. Worthless... no human answered. Will NEVER purchase tickets through this joke-of-a-business. They don't give a rat's a** about customer service.
