Hangup call - did not leave message

In the past few weeks, I have been getting calls daily on my direct line from people who are obviously calling from offshore (mostly Indian accents) through a US number.  They never identify themselves...just ask for someone at our parent company.  Most of the people they ask for no longer work here.  I have told them that they are calling my direct line and not the company and to stop calling but all they do is ask for the main number of the company.  I have stopped answering the phone when I see the number on caller ID...if I accidentally pick up, I just say wrong number and hang up.  It is a huge waste of my time~

P.S.  There are calls from other numbers that are exactly the same...foreign accents, asking for people who no longer work for the parent company, etc.  It started about three weeks ago.

Get calls from this number at all time of the day. Who are these monkeys?

This is definitely some sort of offshore sales call center.  They need to get real jobs.  Have these fools blocked.  They call everyday.  Sometimes two / three times a day.  Everyday I ask them to not call again.  Have them blocked or DO NOT PICK UP!

Similar to Exec Assistant but on my Verizon cell. Asked for someone with my first name, but Johnson as the surname. Second time in a week from 2 different #'s. Didn't get the first # though. Use NoMoRObo if its a land line, can't block on verizon cell yet.
