Apple India — fungus detected for my macbook air 2017 - motherboard

Address: Vit Park, Near Inorbit Mall, Hyderabad, Telangana, 500018

Hi there,

I have been using macbook air from last 1.5 years with good care, apparently on one day it stopped working.
I tried powering on the system, but it couldn't.
Then i went to the authorized service center (Conquer technologies, madhapur, hyderabad).
After checking they said that, the rooat cause of the issue is because of fungus on mother board.
Now they are charging 48000 just to fix a problem which is i guess much more than the current mac cost.
