No Service & A Broken Oven

I purchased an oven from Hirshes Ballito and had it installed professionally 6 months ago.

After a few weeks I started getting an error on the screen. I reported the problem and waited 2 weeks for a technician. The technician didnt have the part to repair it. So we waited another 4 weeks. The part arrived and was fitted. This "fixed" the issue. Tech leaves and back to the same problem.

I have been in store, I have called countless times (20+) when I manage to talk to the agent (Kubashnee in Durban) she acts like she doesnt know who I am.

So I am still sitting with an Oven that doesn't work. A very apathetic service rep, a technician who never communicates and I am holding thumbs that at some point they might call me and say we have whatever new part is needed or a new oven for you.

Honestly, I am not sure where to turn at this point. I have never received a call from them, I am following up twice a week without any resolve.
