If there is one thing made very clear during the Alberta Provincial Election in 2012, is that those robo calls suck. And that is perhaps way too polite of a way of saying it.
These calls can be information based, or survey based. And they are well worth it, cost wise, to the folks trying to mass market something. However my right to privacy and to not be harassed, far outweighs marketers rights to information at reduced costs.
When you get these types of calls, you have NO clue if they are who they say they are... And if they want answers to questions, you have no right to offer anything other than a selection of canned answers, usually tuned to give results the caller wants.
I want to know who I am talking to, I want to question what it is about.
And I do NOT want to be hung up on if I don't give an answer you don't like... such as "Are you going to vote for 'x' party?" and you say no, the phone gets slammed down. Excuse me but that is just freaking rude. And I am tired of it.
Change the laws...
