For completeness, just to let you guys know that what I did finally worked and we have got use of our own domain name that someone was squatting on without using it.

Please note that although these two forms
https://support.twitter.com/forms/trademark
https://support.twitter.com/forms/impersonation
were throwing and error messages, it now appears that they were working (at least I THINK that is how Twitter came to life and responded - by email)

Cheers
