Get Paid To Survey
You may want a separate email address for your surveys. Join as many as you can, to increase your chances of qualifying for a survey. They usually pay in cash, points, certificates, gifts etc, with many offering entries for cash/prize drawings.
Get it all off your chest. Tell companies what you really think of them. It'll make you feel better, and they may even listen.
