Thanks for doing the legwork on this. Even tho I won't answer nor return unrecognized numbers like these, I *do* appreciate knowing its origin in the unlikely-event that the caller may be someone I actually want to speak to. I know people all over the world and tho I provide a certain few my cell number for texting only, I have 3 landline numbers and have ignored calls from someone I *had* given my number to a long time ago. I also run a business (one of the numbers) and I never recognize new callers who are new to my company. If they don't leave a message they don't get a call back.
I get calls from them all the time and they keep calling from different numbers so it's hard to block them. I always get a message in Spanish and when I push 1 it sends me to an operator and when they hear me speaking English they hang up on me.
They keep calling me to, they don`t leave no messages at all . I`m really tired of these people,they have called me at least 30 times if not more already !
