I just had three one after another.  I couldn't hear what the caller was saying (with an accent) over some kind of noisy music, like a bar.  He asked for me by name but mis-pronounced it.  I said, "Not here."  The third time I yelled, "What?"  He hung up and didn't call again.

Stop calling my moms number, you upset her she doesn't have a computer. It is a strain for her to answer the phone don't call anymore

You know you're telling a blog to stop calling, right?  Even if she had a computer, this is a scammer, in case you didn't know, phishing for your mother's personal information, like a credit card or anything else stored on a computer.  Don't waste your time answering and let your Mom know not to answer the phone.  Hopefully, she has caller ID.

Scam call - No exchange starts with a "1", let alone "100"! Furthermore, legitimate businesses/people  show their name on Caller ID, not the name of a city or "unknown".

Right on the money, NightMagic!
