Direct Marketing Association
I just got yet another phone sales call and it reminded me to contact the DMA to register on their 'Do Not Contact Service' I thought I would post the details here if there is anyone out there who doesn't know about the service.
If you do fill in the online form don't fill in the email address. It's like giving a box of matches to an arsonist.
It does work but you have to do it again as soon as the calls start happening a few months later.
