This caller hangs up the phone as soon as you respond by picking up the phone and saying something.

same thing.  called me early morning when I would  rather have been sleeping.  wokr me up for nothing

Has called 3 times in the last 2 weeks - same thing as previously reported... I answer, other end hangs up

when I called, this seems to be a security/alarm system company, with an option for a DND list removal - hopefully I will not have to deal with this company again

I bet this is that annoying apex alarm company that calls all the time with an automated message left from time to time
