Just block them....if you have an iphone go to the list of recent callers.....you will see an i to the right of the number....click on that and scroll down.....you will see "block contact"....click on this and they will not be able to call you again....
Just got a phone call 120-714-7996 on my cell phone from Rachel at Credit Card Services.
The call was a recording. The recording asked me to press 1 for further information. I did so to talk to a real person.
When I got to speak to a real person, I asked, "How they got my phone number", they hung up their phone.
My cell number is on the NO Call List. I wonder how they got it.
Got recording from Heather from credit card services. Pressed 0, got live person in what sounded like boiler room setting. Told the I was DNC list and if I ever received another call would contact my lawyer. He laughed and hung up on me.
