Consumer Redressal

Dear Sir, I had bought a Asus Motherboard in Aug'2020 with a warranty of 3 years. Within 9 months of purchase, I had trouble with the motherboard. The computer had frequent blue screen error and the computer used to refuse starting. Because of the Covid pandemic, Asus was not able to provide at-home support and neither had was I able to travel to their service centre. I have been complaining to them from Mar'21 and finally went to the service center 25kms away from my home to give the motherboard for repair. The service team mentioned to provide a replacement or repair in 10 business days. They are complaining that some component on the motherboard is damaged and asking me to pay for it. I haven't damaged any component nor used any equipments on the motherboard since it was under warranty. Right now though i agreed for them to repair the damaged part (which they mentioned approx rupees 700), they are not even replying to my email requesting when I can get the motherboard back. From Mar'21, i have been having trouble and there is no respite from Asus customer support team. Kindly help.
