How to get in touch with Thomas Cook

I previously started sorting out a holiday with Thomas Cook by going into their Nottingham branch. Now I wanted to call to discuss it:

1. The number I found on Google for the Nottingham branch, 0844 335 7542, which I've resisted calling in the past because 0844 is expensive, doesn't actually seem to exist - I got an error tone.
2. So I tried to find the store on their website (http://travelagents.thomascook.com/nottingham-long-row), which doesn't have a phone number.
3. Then I called the general number that is on their site, 01733 224 800, and I after answering about 5 questions in the automated system I got put through to some "Meadow Hotels" or something, who said the switch-boards had been messed up.
4. He then put me through again back to Thomas Cook, I answered some more automated questions and ended up with the Cruise line, where the woman told me she wasn't able to help me, and she wasn't able to give me a number for anyone who could help me, and that I should just call Directory Enquiries.
5. I looked up EE's directory enquiries number, and it costs about £1.50 per enquiry, so I'm not doing that.
6. I then tried again - called the general number, was put through to Meadow Hotels again, who put me through to the real Thomas Cook line, I answered the questions slightly differently to avoid the cruise line, and then just as I thought I was going to get through to a different department who might help, the other end suddenly hung up.
7. I'm now giving up on calling and emailing instead. Thomas Cook seems like an incredibly amateur organisation right now.

I'm including the above list in my email to them. Hopefully they do something about it.
