Refund help
 

I have 4 3park Seaworld tickets which I bought from Orlando ticket deals which has now merged with Attraction Tickets. Seaworld has extended their validity until Dec 2021 and initially we thought we would try and go next summer. That will not be happening now so I would like a refund. I read the info on AT website and it says to send tickets back by registered post and await a refund. Is it really that straightforward can anyone share their experience of a getting a refund. Thanks
