I was fully aware that viagogo is a sell-on ticketing site so was expecting to pay inflated prices. After purchasing two tickets for Ball & Bow at The O2 and receiving a download for my tickets I was concerned, after the reviews I’d read re Viagogo, that my tickets may be invalid. I emailed them and got a prompt, positive, response explaining how their company operated, with a contact phone number should I have any problems at the venue. The person selling the tickets via this site, does not get their money until AFTER the event. Although I was still anxious, I arrived at the venue, tickets were scanned through, perfect seating! Expensive, yes. But it was a sell out show which I desperately wanted to see, and I did!
