Viagogo — I have been charged a huge fee unfairly
I advertised 4 tickets to the Europa league final being played 2 weeks ago here in Stockholm. My ticket listing sold after a few hours of it being active on the viagogo website, but then an hour later was coming another email to say they had been sold again. I tried to find a customer support contact number or email which was very difficult but did send them an email to inform them of their mistake. 3 or 4 days later I got a reply informing me that because I couldn't fulfill both the sales they would charge me a fee for which of course I was not happy about. After a lot more surfing on the net I finally found a contact phone number for which I called and they were telling me I had made 2 listings for 4 tickets on each which was simply not true. The girl then told me I would be charged £30 per ticket total £120. Not happy but there was nothing I could do or say that would change the situation. Then I have just received an email telling me that they have charged me £1450 not the £120 they had originally told me.
I would like to ask if this is a police matter as to me this is nothing short of Criminal and downright fraud?
