This. I get a bunch of robo calls that appear to be for no purpose - there is no way to get a human on the other end of the phone (they just disconnect when you express interest in what they are selling). It's almost like the call itself is a scam, but not on me - like the call centers that offer this service are getting paid to make the call and not the conversion, so they dial my number and play a recording but have no facility to do more than that. Super frustrating.
