Unsatisfactory customer Service

I have my household content insured with PSG Insure. My double door oven was faulty.. A repair man arrived at my home early in August and advised that the top oven element was burnt out which was replaced the next day. This was not the original element.. However the oven was still not working I was then advised the thermostat switch was faulty when replaced the oven was still not working and again incorrect part fitted I was the told that the top element was faulty and will be replaced. I complained to CLC company that handles claims for PSG. that service provider that's Durban TV who cared out the repair replaced the wrong parts and damaged the switches on the oven. I was the advised that Durban TV will collect the appliance and replace the correct parts however my appliance was delivered incomplete they suggested I send the appliance back.. Its gone 1 month I have not heard from CLC or Durban TV. My next action is to report Theft with Saps.
