Xiaomi Mi India - Laptop Damage in just 10 month

I purchased mi notebook horizon ** i* *GB *** GB on **-**-**** by paying **,*** Rs by trusting the company as they claimed to provide good products in India or world. But let me highlights the inside story. After ** month of purchase there was a problem in both USB *.* port, USB Type C and HDMI *.*b. I went to Mi care then submit the laptop. After testing they said your laptop motherboard is also damaged. I called on mi customer help care, tell them everything. I confirmed from them that if motherboard of any laptop is damaged, definitely it will affect others parts too. I told them it means my product is totally or partially damaged already. So, I ask why should I accept that damaged laptop. They said we will fix the laptop by changing the motherboard. I asked why are you changing only my motherboard, you should change all the parts of my laptop. Since motherboard connected to all important part of laptop. I told them that your company provided a damaged machine to me. If you change the motherboard how sure you are that it will not damaged in ** months. And if fortunately, motherboard works well then what about the other parts which are already partially or fully damaged. I will have to pay for all that’s part if they fully damaged in future if products work. I also ask them what is the average life of your products, they said * year and we provide only warrant not guaranty. It means your product life would be * year only after that it would be fully damaged or you have to repair it by paying money. I wasted my money totally.
