Himost Airfryer

I purchased a Airfryer at the end of November 2025 and I was really happy with the product,I used it for making food with all the intended specified uses the product does not allow for cleaning of food spills when making chicken in it and the lid later became defective but I still continued using it but then when I switched it on,there was a burning smell,meaning a electrical fault,now the supplier is saying this is due to electrical surges or corrosion but all my electrical devices is working normally,in the space of 2 months this product deserted me and they refuse to repair the product
