This number comes up on my phone as MEXICO with this code 201 003 6003. It is a hindu person with a very  heavy accent claiming to be a computer tech and wanting to get into your computer files and codes. This is a SCAM. A FRAUD. I DID NOT LET THEM REMOTELY ACCESS MY COMPUTER. IF YOU RECEIVE SUCH A CALL DO THE SAME HANG UP, BLOCK NUMBER, and whatever you do please do not let them access your computer registry items. WARNING.
