Failure to Repair and Communicate

so last year around this time I took a household content insurance cover with Mastercare, I have been paying for more than 10 months, I have been paying well no late or missed payment and never claimed until end of march, it was for my microwave that had stopped working, FYI it was worth R1500 and I have been paying R300 monthly, firstly they took over 5 days to send a technician to asses, and when he did came to assess he took it on the 05 April and promised to bring it back after 2 days coz it was a small thing, that was not the case as they gave me diffrent stories daily until we went for the eater holidays (19 April), we got back an still they gave me stories now telling me they fixed it but sent it to the wrong address, eventually they did deliver on the 03 May after I threated them about hellopeter, but the Microwave was not fixed instead it was vandalized by them with missing parts. I logged a call of complaining and they acted disappointed with their technicians and promised to log a new call with a different one who will fix it, I waited and waited and no one came and I got tired of calling them to follow up and Guess what? they also stopped calling me or trying to pick it up an as things stand all I have to Say in Mastercare appliance and Household insurance company is one big ****. they only want you to sign the contract and will say all the right things until you sign and they fail to fix or replace a simple thing as a Microwave.
