No message left on phone, hung up

Didn't talk after several "hello's"... just hung up.  Most likely a robot call.

Calls multiple times a day.  We do not answer.  They have been calling twice in a row, probably to get around the "Do Not Disturb" settings on IPhones.

After saying hello several times a woman asked to speak to me or mrs (garbled name). It didn't even sound close to my last name and when I told her wrong number she acted like I was being dishonest. Blocking this number.
