Nykaa.com — Prepaid order returned without update and no revert on refund

This company is purely running on stealing money and fraud.. They kept my shipment nearby before delivering for a week and returned without any information or update or call just returned the prepaid order which was of 2353 and delivered only 3 items and rest are not known till date.. They are not reverting over email.. Or support or social media or grievance officer.. I am being tortured mentally not knowing if these refund will ever be done.. Now the shipment show return manifest but no refund details showing
