Looking to buy an iPhone 13 mini in India new or refurbished

I'm looking to buy an iPhone 13 mini in India, preferably 256GB, although 128GB would also work.

Since Apple has discontinued the model, I'm open to:

New/sealed

Open-box

Certified refurbished

Pre-owned in excellent condition

I'm located in Mumbai and would prefer a seller that provides a proper GST invoice, warranty and a clear return/replacement policy if available.

Has anyone recently purchased an iPhone 13 mini from Cashify, Maple, Amazon, Flipkart or another reliable seller? I'd appreciate recommendations based on personal experience.

Or if anyone wants to sell their current 13 mini, Would appreciate it too.

For refurbished or used devices, I'm particularly concerned about:

Battery health

Replaced or non-original parts

Face ID and True Tone functionality

India versus imported variant

Activation Lock and IMEI verification

Warranty and return experience

Thanks
