OnePlus India — Repeated software corruption

This is to bring into your notice that i had bought one plus 9 pro on 2-july-2021 from an authorised dealer. But for my surprise its software got corrupted on 19-sept-2021. Hence, i got it fixed from one of your service centre located in Shipra mall, Ghaziabad. But again today i.e. on 29-sept-2021, software has again gone corrupted.
This was my first experience that a phone belonging to such reputed brand has shown up this way. I do not trust this product anymore and want a compensation against this. Please replace this product as soon as possible because many of my important commitments are stuck due to this problem.
I’m attaching the phone’s bill along. I need revert on an urgent basis pls.
