Who called from 4085855267

carpet cleaning - I stated that they had reached a business hoping they would not call again, as blocking doesn't work when they use fake numbers

I very seldom keep my iPhone connected, but of course, when I did today, this robocall showed up as "Sunnyvale, CA".  I've blocked unknown numbers from using the ringtones.  Now I've blocked this number entirely.

Prerecorded carpet cleaner call, I hung up right away.

Unwanted call from this phone number: 408-585-5267

I have taken a different approach, I let the message play out, it repeats and then I do not hang up... they (callers) are about volume, if you hang up, they can quickly get on to the next person...but if their time is wasted on the line, they cannot move on as quickly ...eventually their ROI on their robo calls will diminish...  Its a theory I am hopeful is effective.
