Women with their problems, I wonder why some people find it difficult to listen, atleast even if you want to retaliate, hear from the horse's mouth first. Your land lady deserves that embarrassment, next time she would learn how to listen before reacting.
What happened to your guardian's son is the reason why I am scared of doing phone business, he was lucky you are a caring uncle. If you had not intervened, only God knows what they would have done to him
