What's the point of Photoradar having a contact us page if the people you contact don't reply?

I kind of get the feeling they can't be bothered, like it is too much hassle (even if this is not the case); someone please tell me otherwise.
I understand that they probably get a lot of emails and are busy running this site but come on, even if they can't reply in full a short reply to say they have received my enquiry and will get back to me in due course would suffice.
Maybe waiting three weeks for a response is not enough time, maybe I should be more generous with their response time. Can I expect a reply any time in the near future or am I just expecting far too much?
Rant over....sorry guys and girls.
