Who called from 4259982872

Person with a very strong middle eastern accent called my cell phone stating they had detected very serious problems on my computer.  I hung up on  him.

Called on my cell @ 3:45 pm and hung up without saying anything.

Middle eastern accent, called about a computer virus on my windows machine. I have a Mac but whatever. He wanted me to go to a web address and I refused, demanded that he tell me how he got my name and number and he got very angry. Hung up on him that.

Called my cell, didn't leave a message. How are they getting our cell numbers?????????

Called but left no message
