Received an envelope with order confirmation but no tickets. Wrongly assumed the order confirmation was what was needed to get into venue (had seat numbers on reference number etc) when arriving was advised that we needed physical tickets. Called viagogo straight away and sent through everything we had. They were awful said we "couldn't prove" their seller hadn't sent the tickets in the tracked envelope so lost £300 found out from venue that they are not registered as one of their sellers, the tickets we were supposed to have face value was £120 not £300 and they have this issue a lot. The man on phone was rude and said wouldn't investigate as I couldn't prove it. Perfect scam send the tracked envelope with no tickets and viagogo will back you up as you can't prove the tickets weren't there. Sent to action fraud police website and credit card company to investigate. Viagogo said as I couldn't send the empty envelope (recycled) even though I had delivery note/order confirmations sent etc wouldn't help. Not sure how me sending a picture of the empty envelope would have proven that tickets not in there. Avoid avoid avoid. Viagogo is a middle man with no sight of the tickets sent (or is this case not) via seller so open to so many scammers who will then be protected by viagogo and you can't prove that they didn't include tickets. Sure the good reviews are that there are genuine sellers but you have no contact with seller and no way of vetting them so zero chance of being able to forsee what could happen. Listen to the majority of reviews that are one star and don't risk it
