They do operate from two numbers. The other number is 813-400-1149. They call at least once a day. I finally answered today, and went through the automated call. Even though I pushed #3 ,for the person not at this number it still took me to a live person. The person was very rude and nasty, even though I was friendly to her. She told me that my number would be removed within 48 hours. I don't think that will happen, so I just blocked both numbers.

I am on the "Do not call"registry and this fool calls everyday!!  I have blocked the number but that doesn't prevent them from leaving voice mail.

mrs olga yhey called to my house at all time   i put the ansuwer  maching and they don  speak    i don want  this calls any more

813-400-1127 and 813-400-1149 call my number theres a recorded message "stay on the line for a very important call" , so I think if its really important why isn't there a human on the other end when I answer.
I disconnect and when I return call those numbers I get a recording "number is not in service at this time".
How do I stop these fraudulent calls??
