So, I am getting these annoying calls too. They did identify as CBE and then asked for someone else.
They have also used 816 659 1155 & 312 951 1276 & 425 390 8105 when I have answered to tell them to stop calling they always ask for a different person.
This is getting beyond annoying!
I see that this number called me on my cell phone today the 15th. I did not take it, as I was not near my phone at the time. Google it and here I am. Thanks to all for the information. I actually live in the 515 area code.
