Who called from 5303660174

Watch out! This was an unsolicited text message:  "Up to $200 Gas Giftcard CAN BE YOURS. Call 877-499-0316. Reply END to unsubscribe." I NEVER SUBSCRIBED TO THESE JOKERS IN THE FIRST PLACE.

I never subscribed to this whatever it is.  How did they get my number to text me.

Received similar "via Bluetooth" on my Verizon cell.

I got a similar message, but mine read:
"Congratulations! As a thank you, call 877-499-0316 to receive your $100 retail rebate.  Reply END to STOP."

I never signed up for anything like this - I do not give out my cell number to just anyone...
