National Rail Olympics ticket address change problems

GeneerWolf

I'm reaching the point where I'm at my wits end and was wondering if anyone can advise.
Back in March I bought a number of train tickets for travel to the Olympics.
In May, I moved house unexpectedly, and tried to get the delivery address for the tickets changed...and that's when the fun started.
First of all I followed the link on the website, which let me change the address and sent an email confirmation. All seemed well, however several weeks later I logged in to the Nation Rail Games Travel website to check something and discovered the tickets still had the same address listed.
Confused by this I contacted the National Rail Ticket Enquiries helpline, only to be told that since it's my account they can't tell me what address the tickets will be sent to, or change it if it's wrong. They told me to email them directly to get it sorted out. The person dealing with it didn't seem to have a clue and couldn't get me off the phone fast enough.
Of course when I emailed I got no reply.
Annoyed by this and unable to see who else I could contact, I decided to fill in the online complaint form and ask how I was supposed to sort this out, and why it was so difficult to do something so simple.
They replied and told me to go to the Train Operating Company, because they handle the tickets. I was even told that the National Rail website just took me to the TOC's website when ordering the tickets anyway, which is incorrect. Funnily enough when I tried the TOC website (First Great Western) they had no record of any order because it wasn't done through them.
In frustration I tried emailing Atos, whose email address is on the National Rail Games site, who told me to phone them instead.
I phoned them, told them the problem, and was put on hold several times, then told they would ring me back.
As you can guess...they didn't ring back.
Today I've tried them again, and been told to use a link they would email me, and then log in again to check the address is changed. They emailed me the link, which just took me to the same form again. Went through all that again, logged in again...no change.
Phoned to ask for a line manager as instructed. Line manager not available. Please email us instead and we'll sort it out...
Emailed, and no response.
After all the runaround I am amazed that these people can't do something as simple as check an address. I seem to have dealt with about four different companies, all of whom haven't had a clue how to fix this. I'm preparing to set up mail redirection in an attempt to intercept the tickets, but am less than impressed at having to pay for this just because these clowns can't change the address.
I'm wondering if I can charge them for this unnecessary mail redirection, plus I'm wondering if I can take them to court for the cost of the tickets and the cost of the Olympics events missed if the tickets don't arrive.
Does anyone have any experience with taking National Rail to court?
