I've dove with Reggae and I had zero problems, it shocks me that this happened to you.
I think that most people who go to Coron expect to be able to penetrate a wreck at least partially, even if they aren't wreck trained. You don't require wreck training (although your insurance might not cover you), it's just a very good idea. How many small caves have I been into without cave training? Or deployed SMBs. Or the time I went to 25m with just an open water cert. Or, hell, I am not a PADI Boat Diver yet I've dove off of boats my whole career. The other guys nailed it on the head, that if you're uncomfortable you can end the dive. I was asked if I wanted to go through a long swim through on a dive once and I declined twice, I just wasn't comfortable or confident that day so it wasn't for me, and not once did anyone make me question my decision afterwards. I'm a Health and Safety professional in real life, and at the end of the day YOU are responsible for YOUR own safety, and everyone has different risk tolerances. I'm not saying that I would take uncertified or unqualified divers into a wreck if I was the guide, but nothing is to say that even if someone is qualified that they are competent.
