Who called from 4803600215

This number calls me at least 3 times a week.  Leaves no message.

This number calls weekly, no message.  I call it back and get out of service message.  Obviously a scammer.

Calls and leaves no message, annoying.

Incessant calls - Then hangs up. It seems as if putting your info and complaints on the Do Not Call list actually increases the number of these parasitic callers....Hmmmm.

I answered this time, but the caller didn't say anything, just hung up.  I can block about 30 calls, but that is not nearly enough for all the calls like this one.  It's so frustrating!!!
