This call came yesterday,  April 15th, first time.  I missed the call but when accidently pushed the wrong button on my cell and returned the call a recording said I had visited one of their "reward" websites and want to give me a $100 gift card good for many locations.  If interested press 1, if I wish to be put on their do not call list press 2.  I pressed 2 and hung up.l  My question is how would a website I visited know my cell number????

One ring and then hangup.  If you call back, you'll find it's "Reward Redemption" - an outfit that clearly is up to no good as they change their phone numbers every so often - probably due to complaints and running from the law.

Called my Cell Phone.  Didn't answer.  I don't give out  this number so am sure it is a scam of some sort.......

Called my cell number, no message. I do not give out cell, must be a scam.

1 Ring then hangup.  Didn't return call
