Keeps calling!

Just got a call from them, per another site they are a survey agency from Cambridge MA.  They tell you if you don't want them to call, that YOU have to go to their website and de-list yourself.  I call bull hockey on that!  Just got a call blocking by number phone--this is going to make my life much easier.  They're my first blocked caller!

Ignore callers that you are not familiar with & keep your fingers crossed they don't leave you an unwanted message.  

Grocery store survey-wanted to know names of local grocery stores and which one I shop in most.  Said survey was monitored by an 'immediate supervisor'.

This number keeps calling me, they don't leave a message. Caller id shows it as 'Cambridge, MA.'
