<prompt> Human: My father passed away about a year ago and even though he had little to nothing in his estate I managed to pay off most of the debt that included hospital bills and credit cards.Last week out of the blue the debt collection company called and told me they had debt from the hospital which I settled with directly that needed to be settled. I told them not to call me and that I will only communicate via mail. I gave them my P.O. box and have not received anything but they are still calling despite me requesting to only communicate through mail. EDIT: I told them to mail me verification of the debt.Im not obligated to pay this debt correct? My father didnt have enough assets to go through probate so everything was settled within 3-4 months. How do I tell them to stop callingbothering me. Also if they continue to mail me bills what do I do with those?  <response>: You are not responsible for your fathers debts. If the estate is empty, the debt collectors are out of luck. State to them that estate is closed and theres no money left...if they dont leave you alone you can report them for violating the fair debt collection laws.
