Got a call from this number today about 3:45 PM. He asked about back problems I had reported. He asked if I had Medicare, and I replied Yes. This was my mistake, because I feel this was a call where my answer of YES will be used for illegal purposes. I also got an earlier call from a 916 371-4521. They said absolutely nothing.
I wouldn't bother to list it here, except that I had a call from this same
number except that the last two digits were not 18, but 20, last October.
Probably wise to block the whole exchange, or the hundreds block, if your
device can do that.
I get calls from this number several times a week. But I don't answer and the number is blocked. I check my Caller ID and I can see that they tried to get through. (But my phone never rings). They hang up on answering machine so I'm not sure this particular number is about back braces.
