Sounds like what happened after my Mother-in-Law passed away. We were contacted by the organization that manages the retirement home where she lived. They told us that Mrs. xxx terminated her residence without giving notice, and did we know why she left. At least the jerk on the phone was mildly apologetic when we told him she had died.
Yeah, when my mom passed away this year there were a couple of people that demanded that I put her on the phone to cancel her accounts (health insurance & a credit card). This was after I had told them multiple times that she had died. I told them I was happy to send them a death certificate...but they kept insiting to talk to her.
