Acer India — Notebook thin & light

I have brought the Acer Swift 3 laptop on 5/Jan/2020.
From September onwards the laptop freezes continuously and I need to switch off it forcefully to start again. I have given the Laptop to local Acer service center on October first week. They have told me to replace the motherboard and they have requested a replacement motherboard from the Acer company. Till now I am frequently contacting the local Acer service center and they are informing that they are yet to get the spare motherboard from Acer company. Its being more than 1 month since I have given the laptop for repair and because of this my works are getting affected seriously. I don't have any alternate laptop as well for continuing my works. Kindly look into my issue as early as possible.
