Fox Hunting on 403MHz

Its in the news again! Thieves are jamming the car security remotes, so you can't lock your car/garage/gate.

The jamming of the car remotes by the 'bad guys' is going on all the time in South Africa. Mostly at busy shopping malls. These car thieves are well organised with medium power jamming devices.  Which should be easily detected by Doppler or RDF receivers. It doesn't matter how 'secure' the code is, these 'jammers' work by blocking the receiver from getting the code to lock the car doors.

This apparently cuts down the amount of spam. But does it? The spammers are very adept at 'snarfing' email addresses from web pages and emails. 
So where and to whom do I complain?
