Clicks airfryer

I bought a Kambrook air fryer in November last year.The quality is terrible.The non stick coating is all wearing off.I returned it to the store but was told a refund is only available the first month.I was offer a replacement grill which indicates to me this is a common complaint.I have had various phone calls but still no resolution to the matter.It is now nearly 3 months. Would never recommend this product.
