This number calls my house and hangs up several times every day. It is "not in service" when we call back. It shows on caller ID as "home improvement."
The same thing happens to me . . . . I just tried calling these idiots back but received a "this phone is not in service." Nevertheless, I am reporting this phone number to the FTC.
My 91-year-old Aunt and I receive calls from this number (213) 908-7500) practically on a DAILY BASIS. I have told these idiots to stop calling . . . more than once. Yet we still receive calls from them. At this point, I don't even pick up the phone when it rings anymore . . . I leave the recorder on. These morons do something and have tied up our lines . . . . we can't make outgoing calls . . . heaven forbid I have an emergency with my aunt and can't make a 911 emergency call. There will be LAWSUITS should this happen. You can bet on it.
