I got what I paid for but support is non existent.
I am giving Trainpal a 3 star rating because I did, for the most part, get the tickets I booked, and at a very good price. (I say for the most part, because the last leg via tube was not there, despite the ticket saying that it should have been. Not the end of the world though). I was unable to get through to them with a query though. The helpline was automated and had no applicable options. I am also still waiting for a response to my email. It all worked out at the end of the day, but I can only advise that if you do use them, be very sure of the details before hitting send. I personally will probably not take a chance on them again.
