Who called from 4077770350

missed call, tried to return and am told it cannot be connected as dialed even though I used a one in front of it.

Tele scammer.They want to reduce your credit card interest rate. Just like I want to sell swamp land on mars.

I received 2 calls today and others in the past. How do I prevent them from every calling again. And yes i've already registered with the National Do Not Call Registry.

another UNAVAILABLE caller..... blocked using Brighthouse blocking feature.

I'm amazed that you can still find a payphone!
