Makemyhobby.com — Live aquarium plants

I ordered aquatic plants (details with price listed below) from Make my hobby on 8th November 2020 and paid full (INR 1088) in advance by debit card. Order ID is #304549. The status shows 'processing' :payment received, preparing order. I haven't received the materials and none of my queries are being replied to. I raised complaints ticket, sent info by Whatsapp, used their mail services, nothing induces a response.
