First of all, they will continue to call unless you give them your name or phone number to be removed. DO NOT CALL AND SAY STOP CALLING AND HANG UP.they dont know who you are to stop calling! This place IS NOT telemarketers. When you ask "what do you do" there are different departments! They dont know which you are calling for. If you simply call,give them your phone number and explain you got a missed call ask why you are being called, they will tell you! Remeber they are calling because they want to talk to you for one reason or another. They would be happy to tell you why. I you want the calls to stop, ANSWER THE PHONE and tell them! Or they will keep trying, because that is their job.
and please guys, treat these people with respect. They are human beings simply trying to make a living!
