Flipkart — Delivered Used Apple Mac Air

On 18th may i purchased one apple macbook air 8 gb / 512 gb / m1 laptop from flipkart for rs 104490.00.

On 19th may one used laptop was delivered by their logistics partner. From that day i have been talking to your customer care but no one responded and took my request to check the product or replacement.
Then on 21st may they have accepted our replacement request which was to be delivered by 24th may till now it has not been delivered by their end.
Then on 22nd may your engineer came and he verified the laptop and also assured me that the fault is from the seller end and the mac would be delivered by tomorrow to us and then today morning i got a message and on app tracking id that my replacement is cancelled.
Whenever we call their customer support their executive only ask our concerns and then request us to keep the call on hold for 5 min but they don't replay they suddenly call gets up disconnected every time we call.
I have paid the full amount, hereby enclosed screenshots of product and invoice copy.
