Tanishq — Delay in refund

I have placed an order of mangalsutra of rupees 67091 on 13 october 2023 from the tanishq website . Firtsly no message mail or call came from the tanishq about thw order confirmation or anything . So on sunday when i was tracking my order it was marked as cancelled by tanishq side only so when i called their customer care number they informed me that me that my order was cancelled due to warehouse rejection and i will get my refund withinn 5-7 working days. Its been 6 days already and i haven't received my refund so when i called their customer service number they told me that they will inform me about the refund process via call but no call came to me the other day day they said that i will get the update about refund via mail .. again no mail came ..i dont know when will i get refund i have been asking them daily but no information is given to me please solve my issue and refund my money
