Incoming call location looked odd so I didn't answer (Kansas City KS). Called two more times and didn't leave a msg. On 4th successive call in less than 45sec, I changed my mind and answered with; who is this? They said, "sir I worked on your computer". I hung up. 913-730-0856 calls again and leaves a VM. First a looooooong pause, followed by "Sir, I am your father."  Call me back at this number. Oh, I forgot the number.
OMG! Accent was that of middle eastern. Interweb searches finds this number as "unsafe caller".
**Blocked** The blocked list is growing strong these days.
