Who called from 4194821376

I also keep getting calls from this number and they never leave a message

I also keep getting this call they have called 3 times over the past 2 days, i suppose i should answer it next time.

They called on behalf of one of their clients with a special offer or an offer with the political campaign

I don't know who this is but they won't leave a message and when I call back noone answers!!! Ours really annoying

Meant it's not ours lol
