Bad service

Good day

I have a huge problem with Game and Defy - Newcastle mall. 2 months back whilst cooking, the stove got burnt i.e sparks came out and i went to Game to escalate. A technician was dispatched, he advised that it was a ****roach caused the stove to be damage - tech fixed and replaced some device. We fumigated, then 2 weeks later same problem occurred. And this time when u switch on the stove on the socket, 1 plate is switched on without operating the touch keys. Again we escalated, and we were advised that the tech will be dispatched. My response was that we need a new stove because this one has a problem, the tech said we need to go back to Game for them to approve this - Game said it's the tech that's supposed to write a report for this. Tech never wrote any report. And now we are being sent from pillar to post between these 2 companies. On the 25th November, I left the stove at Game stores for them to find a solution as I was tired of escalating every other week. Today we were called and were advised that there is nothing that can be done as the fault is a coakroach. Stove is still under warranty
