Callers, let's phone ring once or twice and hangs up.  No message

Just received call from this number and only rang once or twice. Called back and some kind of recording about $100 rebate because I recently visited one of their affiliate websites. Of course they don't name the website but there is a number to press to be removed or talk to someone. Sounds fishy and I am sure there is a catch/scam.

Called let the answering service get it no message

Received call. Rang three times, then hung up. No message left. I didn't call back.

Recorded message claiming I visited an "affiliate website" and that I was eligible for $100 gift card.  When I called back, they did not identify their company and asked for my name.  I hung up.
