Hi all and Happy Holidays!
Not sure if this is the right place for this, but worth a try I suppose before I do an OT on the BA forum...
I recently bought a return ticket from "Thetrainline.com" and everything went through just fine - it seemed - until I got my credit card statement today which showed they had charged me twice for the ticket. Grr.

As you can imagine with the Christmas shopping period etc, it has not been a nice surprise to find out about. My bank told me it would be quicker to deal with the Trainline direct for a refund.
Their customer service proved to be totally unhelpful, saying that I would have to send a copy of my credit card statement to them BY POST so that they could issue a refund. I asked whether it was not possible to do this by email - attaching a scanned copy of the statement - and was told "Computer says No". I then asked whether I would be entitled to any compensation for the inconvenience this had caused me: "Computer says No".
Going back to the website I found that their online enquiry form does allow me to attach a document, so I scanned up the statement and sent it off with explanatory details. Now I've calmed down, I'm starting to worry about the wisdom of having done this from security point of view etc.
It is actually the first time this has ever happened to me, so I guess I've been lucky but I'd appreciate any advice from anyone who has had problems with The Trainline, or gotten any compensation from them due to being overcharged etc. I really didn't need this to happen right now.
