Called about some free medical alert alarm something, to press 1 and some other numbers, NEVER DO THIS. It could transfer you to an overseas or long distant call that you'll probably have to pay for. And surely, they won't tell you about it because that's how they get their money, the alarm thing is a scam. Also any phone call that's got unavailable on it is bound to be a scam.

Scam. Blocked.

Called but did not leave a message.

Call call came while unavailable...I will block the number... 18 Mar 2016

Called back, blocking my number.  I got the message that the number was "no longer in service."  Just another scam.
