OnePlus India — Oneplus 9 pro 5G

The mobile less than six months old has conked and i am informed that the mother board is faulty and they don't have spares. They told 10-15 days time for service.
It's surprising that spare parts not available for the latest model and they want 15 days time for repair.
The instrument was given to the service centre in Mumbai on[protected] and no response yet even after 13 days.
A high end phone mother board cracking within six months is a serious issue and they should replace the instrument immediately
