Who called from 2025707755

got 2 calls from 202-570-7755 yesterday - did not answer the first time and than blocked the number and they tried to call back 3 minutes after the first call but my block went into effect.  Panasonic phone system blocks up to 30 numbers.  It rings once than turns into busy signal and caller is than disconnected.  When I did try to call back using *67 of course - it states it is not a valid number - definitly scammers.

I keep getting calls from (202) 570-7755 also; same as "annoyed" - Not sure what this is all about. I heard a voice today--sounded like a young adult (male).

I will NOT answer this phone call.  I check caller ID.They continually bug me. Must be creeps from Wash DC

They called once, I rejected the call.  No voicemail.  It's gotten to the point I don't take any calls on my cell if I don't recognize the number.

It's the RJC.
