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..
