Sorry to say, but I have been reporting these very annoying criminals to DoNotCall for many years with no success.
Maybe someone should initiate a change.org petition to the FTC?
I promised myself not leave more complaints about the security system calls (was getting redundant). But I'm giving in. These calls are now coming in nearly everyday twice a day for a month. I got three calls yesterday.
I mostly been getting these calls using these other two numbers as well:
Get the same calls, always starting just after 8 a.m. Reported the calls (both robo-calls and calls to a Do-Not-Call phone are illegal). WAS ADVISED NOT TO ANSWER SUCH CALLS IN THE FUTURE. The scam operation starts with random calls made by computer. Once you answer, they know they've reached an active number and will call you forever. The "employees" (criminals) asked for your phone number because they did not dial it. The computer did. I answered once, too, and played along hoping to catch them asking for my credit card number. When I said I did not own my own house, they said I didn't "qualify" for their "services." Their computer still calls me at 8a.m. every day.
