KEEP CALLING ME AND WILL NOT SAY ANYTHING

Phone rang, no message left, blocked

I answered this which is something I don't usually do, but I also don't have everyone I know in my phone. The caller identified himself as being in my area selling security systems. I was in the process of telling him that I have a system, but he hung up before I really got it out.

Called but would not say anything
