Missed call, no message left, called back and got this recording: "I'm sorry, your call did not go through. Will you please try your call again later?"
I called a second time and got a recording that said: "Hello and thank you for calling, if you would like to be placed on a do not call list for the number that called you, please press "1" now., I did, Then the recording said: "We are sorry for any inconvenience, please allow up to 48hours to process your request".
This is the 3rd time I get their call, when I answer all I get is silence, got the feeling is a bot searching for real (active) numbers for telemarketing purposes.
