Call my cell and did not leave a message.  I called back from my desk and get a recording that stated to press 9 to be put on do not call list.

Called and did not leave a message - caller unknown

Answered call from this number but no one seemed to be on the other end

Clearly a spam, use the block feature on your phone. Return call yields a message that merely states "Our corporate offices are closed"

I always block my number and call them back just for the [***] and giggles.  Anyway, called back, disconnected.  Called again and got a recording they are Rewards Redemptions (whatever the means) and they called me because I had recently visited one of their affiliate websites (a really be crock - who comes up with these scams?).  Anyway, these are the same scammers using a different number that called me a week or so before.  As fast as you blacklist or block them in our phone, as fast as they change their number and get through.  I recently had to delete some of the older ones from my list.  As I type them a number from 70002 is ringing my cellphone.

Will they never, ever stop.  Who buys into this crap? Do they really make money off this?  Is anyone stupid enough to give personal information to some random a-hole that calls them on the phone?
