Who called from 4124305550

I get a call everyday from this number. Caller ID has the letter  I capitalized. I answered one time and got no response. How can I stop these calls.

I also received a call. But they left no message.

They're calling US too...and we're on the "Do Not Call List"...figures

I want to know if this is real Pa. trooper I have been receiving from them.

Well lets hope nobody you know is in an emergency situation and its life or death and they have to use a strangers phone what you said is just ignorant
