Got a call at 3 pm on my cell phone, they hung up, left no message. ID just said "TX." I called the number back & a recording said "if you are calling this number back, it means you are likely responding to one of our offers.." I hung up & blocked the number.
This group just called me and when I answered my phone it was dead silence. I called it back and it was an automated teller telling me that I could remove my number if I wanted to. I chose the do not call list, considering I'm on the DO NOT CALL Registry. I guess we'll see if I get another random call
It is probably someone in india or something outsourced using a soundboard, as it does seem to respond to any questions you ask, but it is very robotic
