Calls an leaves no message,cannot call back

Another robo-caller.  Some [***] will get a commission if you buy a solar system or another lame product from companies they refer you to.  Is anyone really that stupid to be talked into a cold call sale over the phone?

Keeps calling but no one there.  Annoying

keep getting this idiot caller too...and just hangs up, never leaves message.  sure wish they would go after these creeps

I just want to check my Business 101 acumen.  (1) I own a business (2) I robo-call people to solicit them to partake of my services (3) I don't leave a message describing why I am calling or what my service is about (4) when the prospective customer calls me back, I have disable the function therefore no one knows about my business or my services. WTF?
