This caller has called my cell phone 5 times in two days, never leaving a message. I have not answered any of their call attempts. Very few (and only trusted) people have the number this caller called me on. It seems likely to be a robo-call.
This number has called me 14 times or more a day. They claim to be part of the diabetes association, but I don't believe that is true. They are trying to "sell" an "upgraded meter".
This number called first time didn't answer. It was received a second time a hour later, answered this time but no one spoke and sound as if I was in a hollow place .
