I've tried their contact page, it's not terribly helpful.

They've plagued me for years asking me to advertise with them, I won't because they haven't got a location anywhere near me.

I've just discovered that an ad with my phone number on it has been placed last week, the details aren't accurate and the location is a long way away. It claims incalls when I don't offer them and is totally misleading.

No wonder I've been getting calls from guys for that location.

Anyone any idea how to contact them directly, or at least get a fast response?

Hi

Check your email including junk mail, you should have an email from them telling you they created an ad. There'll be a link in the email where you can see the ad & then you should be able to delete it.

I do have such a link but it's not for the ad which has been posted.

The actual ad uses an image from the Loot, plus a write up that's sort of me, but contains a lot of seriously incorrect and misleading details.

I emailed them and got my old ad removed...but the main reason I wanted it removed was to get rid of my work number off Google... They removed the ad but the bloody number is still there!  grrr.
Good luck x
