Avita — Laptop Hanged

I recently bought avita laptop on March 28th 2022.Just after a month of it's usage it suddenly hanged off. I called the customer service they sent the technician nearly after 8days after my call. Technician thoroughly checked and told me that there was an issue with mother board and have to replace that part and they will order it soon it will be resolved. It's been a month and there was no more response from their end. I doubt the company authenticity if they sell such a disgusting products.
