I received multiple calls during the day from this number ... the caller has no ID or leaves a message... I suggest don't answer it and block it if you can; certainly don't call it back that only provides your number as being an active number.
I received a call from this number (Caller ID said "Washington DC") at 6:00 in the morning! I didn't answer, they called back at 6:10. I was so angry!!!!! Then they called AGAIN at 7:45 (all the same morning) so I answered and immediately told them "Take me off of your list". After I said that a man said "Hello?" so I screamed it at him again and how dare they call at 6 in the morning and hung up. I have no idea who they were or what they were going to try to scam but they are now blocked from calling me again.
I now block every single number that I'm not familiar with as soon as it stops ringing on my cell and landline. 6am is illegal anyway. People can legally call between 8am-9pm. I'd report it. It can't hurt. It's scary when it rings so early. Most think there's an emergency. In that case they'd leave you a voicemail or message. If I'm in the mood I'll pick up and play along. I act very sweet and naive-even if it's a rude bill collector or something like a rip off "won a trip" spiel. At the completion, still acting dumb and agreeable but quickly switch it up. I then curse them out and belittle their job and immediately hang up on them. Actually wait to hang up until they're in the middle of their usual rude or overly sweet response then block the # right away. Good feeling. I never answer Unknown Callers at all. They never leave a message anyway so obviously they moved to the next victim on their list. If anyone keeps calling call your carrier. They are supposed to help. If they don't it's because they're lazy. Ask for their supervisor. Good luck!
