received a call from (202)495-7138 about 1 hr ago but I missed the call but there was no voicemail. my caller id said DC, USA. after researching the number I'm glad I didn't call back. these telemarketers get craftier and craftier every time.
Got a call from this number and I didn't answer. I called it back and had the option to opt out of their promotions and to go on their do-not-call list. They haven't called back.
