I ordered a hookah on 12th january 2020 worth rs 1999 (Jaipurcrafts royal rajasthan 22 inches brass hookah). It was damaged so i made a replacement request l. But then i changed my mind and decided to return it. It was picked up from my place on 21st january. I returned the product with all the tags, and with the exact same packaging. But they never gave my refund. I have been contacting amazon since 24 days, but haven’t received my refund yet. I am done and tired contacting amazon customer care. I am so disappointed with them. There site says that they refund the amount in 5-6 business days. But i have been waiting since 24 days and haven’t received my refund.
