calls and hangs up

Seems like these people are a SCAM for sure!!!!  Have had several of these calls last couple of days, and when I don't answer, they hang up on my voicemail.  Actually did leave one message for me to return phone call about an "important bussiness matter" though.  Obviously, I didn't call them back.  I'm glad I was able to this site to confirm that it is a SCAM!!!!

I live in Canada and got a call from the above number but, I was away when the call came so it went to the answer machine so when I tried to retrieve the message it called that number just as I pressed the button to listen to the message.

I use a prepaid cell phone, the only reason I have it is because I am disabled, and I have ESRD and am awaiting a Kidney transplant and I need a way for my transplant center to reach me, I have a rare blood type B- and have been on "the list" for five years this past March, I would like to answer and cuss them out but good but I can't afford that since I prepay for my minutes and my phone is for emergency use and for a transplant.

I also get junk text msgs which cost me money I communicate with friends and family with email, Twitter, Facebook and land line I DO NOT TEXT. Every junk text msg is a scam and costs me half a minute which I have to replace monthly or I lose my phone service and number do you know how many Drs hosp clinics I'd have to contact with a new cell number.

These people are [***]-suckers and should get a real life and a real job!

Got a call from 971-208-9947, but did not answer this time.
