thanks, that worked. I didn't know I could do that!!

Received a call from this number early today, threatening that they would file court paperwork if we did not call back by the close of business today.   The caller said this was in reference to bank fraud & when I returned the call to ask who they were & what they were referring to, the man on the phone said I called  'Global Acquisitions'.   Then when I suggested he speak with my attorney, he hung up on me.  Would like to file a formal complaint against this company if anyone can tell me how to do that!

received call 2;00 pm today.  very heavy accent…said they were from microsoft…hung up…third call

Received their call at 3:12 AM.  Not a happy camper, as the phone rings in my bed room also.  I tried to call the number back to complain and the message said the number was not in service.

Got a call from this number at 9:00 am.  Very heavy accent saying he was calling from Microsoft Windows have regarding a virus report on my computer.  He will show me how to get rid of the virus.....  I asked "what kind of computer do you think I have?"  Dead silence, line still open..... I hung up and redialed the number, said the number is not in service.  
I activated the call screening on my phone thanks to Kat's posting above:
"dialed *60, on my Landline, pressed 2, then # to have the last number added to my "Call Screening" List! Now, if they call back, they'll get a message, telling them that, "The Party You Are Trying To Reach Is Not Currently Accepting Calls From This Number"!"  Thank you Kat!!!!
