This number call me and a guy said his name is Roger Paris,  saying I'm a winner of $500 gift card, and I will get it in three business days. But first I have to give some information, and he asked me which card I'm using, so I knew it was a scam I told him that I don't know my card number and he hang up on me

Just got a call from this number, didn't answer due to being at work. The number called back once I was off when I answered I asked who it was however they didn't want to give me any type of info, they said they where calling to see how I like my service with some company I've never heard of.. At that point I just ended the phone call

They did a hang up call to my cell phone.  I didn't answer, because I was busy.

'Billy Hernandez' keeps calling at odd hours, complains he gets hung up on every time he calls, claims to be a 'friend from the post office''. He always hangs up when I ask him what scam is he running for the day. These vultures prey on old people, as it's my Sr citizen mom's # he keeps calling. I'd like to file harassment charges on this organization or whatever it is.

Same here, hangs up when I say it's a scam. Today though he tries to say he's a friend from the post office.
