It's a Scam....

Called my house several times claiming that I'd won a 2013 Mercedes.  Asked that I go to Walmart, buy a Money Pak Scratch Card? worth $299 and report back.  Caller referred to himself as "James MacDonald".

scam and they will not stop calling

After reading these comments they must be the same people calling me from different 876 (jamaica) area code numbers. Sometimes the call is unknown are restricted. Got a restricted number call and they left a voice mail to call back @876 etc. said I won 42 million dollars and a Mercedes. I never answer calls I don't know. Add them as scam and click on the option to send call to voicemail. That way phone doesn't ring and only notifies me if I have voicemail. Otherwise it just shows up as missed in my call log.
