Last year, my sister bought tickets for T in the Park festival and she enjoyed it so much, she bought another one for this year. She paid 200 GBP for 2 tickets last month... and they still haven't come yet. What made me angry was that my sister didn't want to send an email asking why the tickets haven't arrived yet because "she doesn't want to bother the seller" until I nagged her and she sent the email last week. She replied saying that she sent it already and considering it was the same week that the post office in the UK held a strike for a day, we accepted that as her reason but with that said, my sister spent another 200 GBP in case the ticket hasn't arrived. And so, with the festival starting tomorrow and the first tickets she bought still hasn't arrived (but the second tickets she bought arrived on Tuesday) she's now asking me to help her but I have no idea what to do first. She did pay by paypal but I don't know if it's 1. The seller's fault for grabbing the money and running off but fobbing off with excuses 2. The post office's fault and maybe I can work it into a "I MISSED THE MOST IMPORTANT EVENT OF MY LIFE"
