Vibecrafts — Nested center table

I ordered nested center table with metal legs and marble top from Vibecrafts (online) by paying 18, 619.05 Rs.
Received the product with marble top broken in to 2 pieces. Raised request on the same day for return. Also followed up on watsapp many time. on 19 Jan 24 they said they will provide replacement of broken marble top. I received replacement on 4 Feb 24 and that marble piece is also broken in to 2 pieces.
I tried many times by sending mails and watsapp messages in these days but no asnwer.
I need refund of my 18, 619.05 Rs.
