Received call requesting information on my wife's prescription meds. Caller claimed to represent a health advocacy organization I had never heard of. I refused to provide any information or even confirm identity. The caller became abusive when I politely requested to be removed from their call register. She laughed and mocked me so I simply told her "this is the last time you will successfully ring this number" and issued a block through my phone carrier (ooma.com). Problem solved...
