My 90 yr old grandma fell ill very suddenly. They think viral meningitis. She is able to talk but is still confused on events. She was released to a rehab place her supplemental insurance will pay for so many days. She was smart and has a POA made listing both her daughters. They get along fine. But because my aunt is not main POA businesses won't let her stop like cable services because she is not main POA. My mom will try to call. They are getting tired. Grandma wants to go home now, but had told my aunt she could sell her house and she would stay in rehab place. I'm looking up home care agencies. Also looked up numbers for aging senior in local area. Who can help my mom and aunt get things handled so they don't lose their minds while they try to keep their jobs at the same time?
A primary POA can authorize someone else to act in their stead for limited actions, much like a competent person can give permission for someone else to speak or act on their behalf. Primary (your aunt?) needs to write a letter that your Mom is authorized to make service level changes, including cancellation, for all utilities at grandma's address. Mail/fax/email a copy of the POA and the POA's letter to the businesses together with your instructions to reduce services.
