annoying pest keeps calling and asking for my deceased mother in law.

Finally found a way to block them!  New free service called nomorobo.com.  Works with most landlines (we have AT&T).  You sign up for free with nomorobo and any robo calls ring once and are then transferred to an automatic message that says you do not accept robo calls and telemarketers.  Works like a charm!

They just called my cell phone and asked me if I was interested in their product, Nature B. Not sure what it is or how they got my number, but I asked them politely but firmly to remove my name from their list because I wasn't interested in anything they'd be trying to sell me. "Nancy" said she'd remove my number and to have a good day. If you do answer their calls, try being firm and polite.  

Called my cell phone eight time today. Call back number lady answered Nature B.

NATURE B.  SHE CALLED MY JOB

V pollen I think that's what she said some food supplement that blah blah blah (click)

They hung up before I could answer.
