Who called from 7203707524

Got daily calls for the past three days - leaves voicemail that says "Hi this is Michelle on a recorded line, how are you doing today".
Each and every time.
Pretty sure it's spam.

Same as above once I answer sounds like a robot.

STOP CALLING ME

Do you really and truly believe that the person that is calling you will actually see that post and somehow magically know who to stop calling?  Did you put any thought into that post?  My guess would be no.

Call and listen but wont say anything. Calls all hours of the day. Like they are checking to see if the house is empty.
