I stayed on the line long enough to ask which of my accounts they were calling about. Not being able to give me a number, I told the caller, it's not a credit *what ever* company, they were a scam company, SCAM SCAM SCAM. He started yelling at me, I hung up! HA--- I pissed them off!
Just discovered this and it works for my phone "problem callers". right after the call, dial *60. then #01#. That will block the last call, until you remove it. Also, dialing *57 right after the call, will trace the call and send it to your provider's security department. After three such calls, the caller will get a warning from the police.
To who it my concern, I received a phone called then was told to push 1 someone answered saying "Account Services" I asked how you got my number. They called on my home phone. If they called on 800# the block would work but they us and area code.
You can block any number, even one with an area code. I did, and it has worked. Or, if you prefer, you can order Zap Guy's device - shock and awe:) Delightfully retaliative idea.
