Good deal turned sour

I joined Discovery Insurance as they offered a good deal with some savings.

Needless to say after joining I was contacted to tell me an evaluator needs to come out and view my insured home contents. After this assessment I was emailed to advise my premium would be going up by R2000! An old Apple Watch, which was the first ever release and 1 iPhone 7 equates to an additional R500 per month (which I don’t need or want to be insured) and the rest as apparently I need an extra 3 million rand for contents. Yes I’m also gobsmacked confused and living in a small townhouse. To date no one will share this evaluation assessment with me as I get handed from agent to agent for the past 2 weeks. Also putting me in bad sense of comfort as should there be a claim I can guarantee you Discovery will tell me you were so called underinsured as per THERE records when I know I’m not! I am trying to dispute this BS but I can’t even get someone to help me get alone show me this assessment and mental costings. I shudder to think if I have a claim. Right now I’m thinking of cancelling to be safe and just go back to where I was, at least then I wasn’t being forced to increase my insurance to something I don’t have or inflated replacement values.
