Bad service

I bought a 3 piece stove at Game on the 23rd November 2019. I had it installed by an electrician and the stove plates only worked for a few days and thereafter it didn’t work. I went to report the stove on the 19th at Game Gateway and they sent a Defy technician and the technician failed the stove and said we needed a new stove and we reported this at Game Gateway on the 24th December and they told me they will call back once they communicate with the technicians. Since the 24th till now I have been going to Game to enquire about my new stove and they still say they will call me back. I have been waiting for their call and nothing. I have been without a stove since before Christmas and I am really frustrated. I have been cooking on a 2 plate stove I had to buy when I spent more than R6000 on a brand new stove. I am fed up now
