It appears "KBL" or "Key Benefits" has a new number today - 901-562-1601. They just called my cell again (which is registered in the National Do-Not-Call Registry) but did not leave a message. If you are getting similar calls and you are registered, I encourage you to go to http://www.fcc.gov/cgb/donotcall/ for instructions on filing a complaint.
I told them not to call back & to take my number off their call list. The following day, the Supervisor called harassing me for information, even after I told him that I requested no further calls. They are calling many times per day over the past week.
I keep receiving phone calls from this number showing from Memphis TN 901-562-1601. They call and call and call. I am registered on the Do Not Call List and they still call. They inquire about my master card, they have the last four numbers, and they have my address. I had the same calls from a number out of Las Vegas. It is clearly a foriegn group of scammers.
