Rang and I answered. Hung up so I called back. Got the recording "this is Julie from rewards redemption. You recently visited an affiliate website and we have a $100!gift card for you. Press 1 to be transferred to a reward specialist or press 2 to be placed on the do not call list".
Legit ad agency clearinghouse. Same as above about visiting a website; the website was HowToGeek and a legit ad sponsor. Only get a call if you set up a FREE member profile. Connected with a real person (option#1) and said I want to opt out of further offers. Said "No problem" then 20 min later received an email confirming that.
Called and hung up. So since they love to call and waste my time. I decided to call them back and just give them dead air for an hour. Work was slow and it made me smile.
