Other websites identify the caller as Delta Outsource Group, a collection agency. Not sure they are legitimate. May go by other names, such as Warsaw Group.
This is a company called The Deltqa Group. They called my home tonight for the umpteenth time and when I advised that the person wasn't here and ask to take a message they slammed the phone down in my ear. I called back to find out why they are so rude and spoke to a man with the last name Burke. He was polite and professional and said it wasn't him that called me but that he would look into the rude calls. I doubt that will ever happen. I advised that the person they are requesting works overnight and unless a message is left, they will never get a hold of her. I guess we shall see what happens. Completely unprofessional and calling at odd hours of the day and night.
This number is being "Spoofed" by Delta Outsource Group, a collection agency located in O'Fallon, MO. They will try and gather enough information to create an account. Many bank accounts have been drained by this establishment and many "Spoofed" phone numbers have been fraudulently used to aquire information.
