Clovia — Product marked delivered but did not get deliver.

My order ID is 12324196. I ordered it on[protected] and it was marked delivered on[protected] which wasn't delivered to me or anyone I have checked with. The order was a prepaid order of 2487 INR.
When I got the notification for product delivered I contacted customer care for the confusion but did not get any help, they keep saying that the product has been delivered with the otp verification and I should check with someone nearby, I have checked with everyone possible and no one has my package. I have called multiple times to their customer care service, they keep saying that the issue will be resolved in next 24 hours but it has already been 5 months and I still haven't got the product or the refund or any kind of help or mail so far. Please help.
