Been calling every day recently and never leaving a message. I never pick up because I do not know anyone in the 209 region.

An annoying scammer. Be careful.

Well - they called back again today, so I answered and played dumb for their 'computer service scam'.
Nice lady with Indian accent explained that she was calling from 'Best Computer Service', and that my computer was at 'high risk'.  I played along and managed to keep first her and then her 'supervisor' on the line for 15 minutes (a new record).  The supervisor had better English but a similar accent.
(I am retired and apparently easily amused.)
I sat down at my MacBook and tried to cooperate with what they asked.
However, they were frustrated by my inability to find a 'windows start' on the screen or a 'windows key'.
When the supervisor finally realized I was on a Mac he explained that they were not licensed to service Macs.  
I replied that they obviously know that they are criminal-scum.  
They hung up.

Unusual call. I spoke “hello”, computer voiced “goodbye”.  Having issues with AT+T Billing (Mobile Phone and Facebook accounts)

I, too, received a call from this number. A woman with a distinctly foreign accent (India?) called saying she was from Microsoft and that my computer had been sending out error messages and that it would be crashing soon if I did not allow her access to "fix" the errors. I knew she had to be a scammer because my son had recently reformatted my computer and I had installed Panda internet security software, so I just hung up on her and then I noticed a message from Panda saying an intruder was trying to access my wifi network and did I want to allow or deny access? Of course I hit DENY!! Heads up people!! Lots if crooks out there!!

This number 209-794-4843 has been calling my daughter's phone every day for more than a week. She knows not to answer a number she doesn't recognize. I got fed up and answered it and it was some guy who sounded like he was from India with a bunch of other voices (can you say boilerroom)  in the background. The only thing I could understand from him was the word "windows" and "computer." I told him to stop calling. I wish I had the time to mess with him like the guy with the Mac, because that's what I have LOL!
I am on the DNC list, but these people don't care. How stupid can they be. They just keep calling the same number over and over and over.
