Their fax number (according to
www.118.com) is 0207 859 7582 so have a dial around that number and if you have any luck, ask to be put through to the departmant you need. Also you could have a go at this number 01522 341 922 and see where that gets you, on this number don't forget to dial 141 first.
Hope this helps and let us know how you get on.
