I got the same reply, I sent another email back with a collection of photos people had taken of their feeds showing the same problem to show that it wasn't just me having trouble, and pointed out again that their own live chat had admitted they were having technical issues. I asked if, given the images I showed them, they thought it was an acceptable level of service?
They begrudgingly agreed to refund the pass.
They clearly don't read the emails properly and just skim them before pasting a generic reply. Eg suggesting I should have contacted live chat during the game for support, despite my first email saying I'd spoken to live chat and they had told me to send the email.
Anyway if you push again you should get the money back. It's only €7 or whatever but on principle I didn't want them to keep the money.
