Pre-recorded message, suggesting I need to update my "dusty old diabetic meter"

When the caller finally came on the line she said her name was Mary Mitchell and she wanted to replace my old diabetic meter. (BTW this is a robo call, not an actual caller). I asked her to repeat her name which the computer had to translate into spoken language I assume. It then quickly asked if I was the diabetic and I said, "No one in this household is a Diabetic." It then said, "Sorry," and I hung up.

Received calls from this number on 12/4 at 11:30 am, 12/07 at 11:55 am, 12/09 at 9:12 am and 12/11 at 10:21 am.  I never pick up from unknown sources and the person did not leave messages.  I just wish he/she would stop.  Whatever they are trying to do other than to annoy me is not working.

Received multiple calls from this number over the past 10 days. Didn't recognize the caller and only get a busy signal when I try to call back. No voice mail is ever left so I assume it is no one I need to speak with. These posts were helpful to identify it as a scammer!

Two calls in two days picked up by answering machine.
