CHUWI CoreBook XPro + i3-1215u + the problem with the display and video card

Hello.
I bought a laptop on Aliexpress on 02/14/2024.
The sale indicated a 144Hz display and an intel iris xe video card.
but actually in a 60 Hz laptop and an intel uhd video.

Serial number: ZCoBXPIY8H231200018

The seller sent to resolve this issue with the technical support of chuwi because the video card is displayed incorrectly.
How do I turn on the 144hz mode?
And so that the video card is displayed correctly?

Can you send me the exact link of the shop you saw it? because our laptop as you said is UHD. If its our shop we need to modify. And if you are not happy, you can request to send back the computer and a refund, because it was our mistake. But i need to check first if its one of our official shops or is a random reseller.
I asked tech and the card cannot be 144hz only 60hz…

I am sorry
