A very aggresive group of people have been calling my wife claiming at first to be from GTI Holdings, claiming she owed $820 for two separate debts that were written off years ago after her second divorse. They had her SSN and other information. We had to change our bank account information as a precaution. Now they are calling themselves Atlantic Group. They keep calling from blocked numbers leaving voice mails making threats to take her to court. The first phone number they called from was from Camden, AR. 870-498-8243, now they are calling from a 1-800-250-5834 number. She has saved all the voice mails on her phone in case they are needed.
