Has called several times in the past couple of months. Duct cleaning service. I pressed 2 to have my number put on their do not call list. They still call.
Caller ID showed "CLEANIN SERVICE". Since I don't utilize a cleaning company nor want one, I didn't answer. I also don't utilize an answering machine or VM so these telemarketers (if that's what they are) will never know my number is actually assigned to someone. I've since added them to my call blocking device.
I just blocked a number from these people they call themselves Duct Cleaning or Cleaning Services. You block one number they will then call you from another similar number. I will block this number too. No legitimate company does this, but scammers do.
