Haier India Deep Freezer — Indoor Ac

My indoor Ac which was purchased in 2019 caught fire in 2020, suddenly even after it was disconnected from main connection and I suffered a huge loss . When I contacted the company they refused to replace the product and said that it was due to my electricity, but if it was so why my other two Ac did not got effected . I asked them to replace the indoor Ac but they refused, even the vendor who sold the Ac did not help me
