<snip> Any way turned out the lady had fallen down the stairs and tried calling my family member. Because she could not get through we later found out the lady had been shouting for help and the local postman heard her when he was putting post through the letter box. Police turned up, the lady shouted that a neighbor had a key to get in. The lady was taken to hospital for cuts and bruises to her head, arms and legs and damaged one of her knees. When my family member found out what had happened she was absolutely mortified. She still feels guilty to this day for phone blocking the lady.
Morale of this is do not jump to the conclusion of blocking someone's number just because they might get on your nerves due to a few phone calls a day. Your wife's Aunt might be a pain in making trivial phone calls but think of the possibility is something bad was to happen to the Aunt.
