Flipkart — Flipkart making mental harassments- Need Replacement

Hello,
I have actually got the faulty product .order number (OD[protected] which got delivered on Mar 21st 2022 and opted for replacement ([protected]) instead of return on 28th Mar 2022. Looks like that the gravest mistake i have done.
Its been almost 16 days and I am contentiously following up raising multiple support ticket including on social media like twitter but till date the replacement has not been happened.

All of a sudden, today 13th Mar without my concern they have canceled by replacement ([protected]) making me fool all these days. I am totally disappointed with the way this case has been handled.

All I wanted is either to replace or refund
