Phillips air fryer under warranty - Checkers Thabazimbi

My air fryer is still under guarantee / warrantee. But they don't want to replace which I totally understand. I was willing to wait for it to be repaired. The air fryer was taken into the shop on 21 February 2025. Up until today, we have not had any feedback whatsoever, no call, email or anything from the shop. We went to the shop numerous times and every time it's the same story. They can't get hold of the supplier; nobody has any details on how to contact them. On 14 March it will be 3 weeks. I logged a query online, called head office and no luck. I did however miss a call yesterday, received an email and rep**** 3 times but still no feedback. My question is, how long will I have to actually wait for my air fryer to be repaired or even just get feedback? The air fryer is still in the exact same place as where we left it, which means nothing is happening. Terrible after service on their side.
