Not sure who the caller is but they called my mobile number first and when I did not answer they immediately called my home number. They did not leave a message on neither phone.
The phone rang, when I answered, there was no response, just silence - may be unsafe, or hacker...
This # called my mobile, left no message. Has same first six digits as my mobile.
