Terrible communication
I bought tickets on Saturday for my daughter and then within the hour the seller emailed to say he'd already sold them on Ticketmaster and that Twickets could refund me. I emailed them straight away to let them know and I've not heard anything back, I know in theory it's meant to be up to 5 days (which is a ridiculous amount of time to have to wait). So at the moment I am £375 out of pocket and my daughter can't buy another ticket until we receive a refund (which I am assuming we're entitled to, as Twickets haven't got back to me yet, who knows).
I have always been happy to recommend Twickets up until now but I won't again. Communication should be key with this sort of platform but I am just in limbo until they bother to let me know what's happening.
