For the past week, same time, I receive a call from this number. I blocked it. In my opinion this is a scam and something needs to be done to stop these types of calls.
You are the only one who can stop them - Do not answer unknown calls and do not call them back. Consider getting a call blocking device (or app for your cell phone)-they're available online and start around $45. http://800notes.com/nb/search?q=call+blockers
Call blockers do work.
