I have started receiving calls from ACS regarding credit card debt belonging to my father. My sister is getting calls as well because she still uses her maiden name. Our father is very old and ill and resides in a nursing home, and is close to running out of money, so there is no way he can pay this debt. So far I've ignored the calls thanks to caller id, but it is getting annoying. Would they leave me alone if I told them the truth, or try to hit me up for the debt? It is my understanding that I am not responsible for this.
