Discovery Insurance horrible double standards

I am insured for such a long time, discovery replaced my gate motor without any problems for a total of R12000 roughly. Our gas oven packed up not due to loadshedding, WE DONT GET LOADSHEDDING FOR THE LAST 2 YEARS and we have a solar inverter that protects our appliances. I logged a claim with them for the over as the door is not sealing, the oven is dead and the top plates wont ignite properly. I always feel bad claiming but an oven is such an important item as its our lively hood for food etc. Discovery declined my claim saying its normal ware and tare. This is a load of bull****, the gate motor was also ware and tear in fact a gate motor works harder than a damn oven. So this is really not on, I even went and today got a new oven which i can send them the quite for a special R8999 so that they wont have to approve a massive claim im a modest person but yet they rejected our claim, but they pay geysers, gate motors for R12000 but wont replace a R8999 oven????????????????????

Can a supervisor please call me, I would like to cancel my insurance with discovery IMMEDIATELY coz if something else breaks regarding my house and they don't pay i am gonna be struggling as this R8999 for the oven we bought today was a huge chunk out of our house hold budget, I have a new insurance company that are willing to pay the claim so please can someone call me to cancel my discovery insurance.

The consultant I spoke to I asked him to let a supervisor call me, they flat ignored me no one called me.
