called from 6410 and 6411 the same day - I believe this is the "Say Yes" scammers.

Caller unknown therefore call not answered.  No message was left.

This number calls us several times daily.  We don't respond as no caller i.d. is shown.

Multiple daily calls

There are a number of calls coming in associated with this phone number (703)382-64XX.. Last 2 digits always change. They are spam calls, robo calls, phishing calls, call them whatever the hell you want. These extortionists call every single day with the last 2 digits of the phone number changing. No matter how many times you block it, they call back with a new number. It's frustrating and sometimes I answer but I stay silent on the phone just to listen to any background noise or anything suspicious.. Now a days, they can record you voice to use that against you for there scams. Stronly suggest to block these calls..
