I keep getting calls from this number so today I decided to phone back.  It is a call from MedCare regarding diabetic supplies.  We do not use diabetic supplies so asked the man why we are on his list.  He said I had taken an online survey and that is how they got my number.  He knew my name, number, address and email address and I do NOT take online surveys.  Watch out because this seems a little strange to me.  I'm wondering what company we do deal with might have given him my information???
