Paid per credit card on 7/21/2015 for the 9/23/2015 Kraftwerk concert at Elie Caulkins Opera House in Denver. This was for $215.50 for "discounted tickets! Confirmation Order came in with notice 2 tickets forthcoming. Week before concert called them at their listed # on line and person stated tickets were usually held at box office. Nite of concert box office manager stated they were 3rd party seller, no tickets for us under our name, no entry. We waited 2 months for this concert and I had to take a crushed and disappointed son home, a major Kraftwerk fan. We checked per Google and discovered this is a common issue with this company, they are even being investigated in Illinois for tagging extra charges surreptitiously on their billings. If U have to pay a little extra for a reliable company to get tickets, do it. Stay away from these scum.
