Not sure who this is either. Have received multiple times, shown on Recents list as from Ada, OH. Same location as (419) 558-5480, with last digit being only difference.
I received the first of three calls from this number on 3/15/17. Is shows that it is originating from Ada, Ohio. Since they don't leave a voice message I just ignore it since I have not gotten any more calls since then. I NEVER answer a call I don't recognize. And I NEVER call back a number that does not leave a message. Too many scams out there. Some of the scams just want a recording of your voice. Don't ever speak to anyone you don't know or did not call. Simply answering lets scammers know they have someone who is a potential mark. If it is a legitimate call they will leave a message. It is just that simple.
