Amazon India — Not received refund on my cancelled order

I ordered a study table from Indian Amar on 13th May, 2022 but due to its low quality I returned it on 18th May, 2022. The replacement item I was supposed to receive was not delivered
nor showed any updates in the Amazon app. Therefore I cancelled the order on 1st june, 2022. Now its 10 june, 2022 and I haven't received any refund nor any updates on the refund status. I have contacted customer care but they did not give me a proper reply. Please look into this matter and reply asap.
