Chuwi core book Pro not getting connected to wireless network

I purchased Chuwi Core Book Pro in may 2021, still under warranty. Since yesterday none of the wireless networks are visible, tried updating the drivers, can’t even reboot the laptop in safe mode , no options, in Settings , It’s Intel i3 processor with 8 GB RAM.
Please help to get at least an address in London where I can take this laptop for service, I am not able to get the service centre number as well. Very bad experience.
work is getting hampered.
need an address pr contact number in London, I purchased this laptop from Amazon UK.

Unless something has changed VERY recently, the nearest place for you to send it for service is Spain. Next closest would be China.
