Ticketmaster complaint: Force customers to pay for their mistake

This experience I had with Ticketmaster makes me never want to spend another cent with them. I don’t care who the artist is playing going forward. that is how upset I am. I can’t believe I am being responsible for Ticketmaster’s mistake. I relisted a ticket for sale with no service fee. I was assured there was no fan to fan selling fee. Of course, I adjusted the price every now and then and the ation page with the payout was always the full amount. One day, the page didn’t work and keeps giving mean error message, so I delisted and listed it again and now the payout include a service fee. I immediately called Ticketmaster to try to revert the changes. Had I known of the change in fees, I would not have changed my prices. I asked to be revert back and was told they don’t have the power to do that. I am like look change it back once, if I do anymore changes feel free to charge me. In this case your tech fucked up and I would not have made that change in any way. Undeterred, the going back and forth happened for 2-3 weeks. I am like wtf? Then it suddenly got sold! So not ticket master is now charging the buyer a higher commission and charging me a higher service fee. I am like dude you need to refund me the fees. I was told it is because I didn’t adhere to the policy, but the policy wasn’t stated anywhere when I first listed, nor was it an email or anything that was sent to me. In the end, Ticketmaster wants me to pay for their mistake. This is fucked up. I don’t know if I want to ever associate myself there ever again, even if Ticketmaster is a monopoly. I would even consider flying to a different country to do it. It is not really about the money, it’s more about the principles at this point. I feel being taken advantage of their systems.
