O3 Plus — Partial product received

Ordered multiple products but did not receive the order ID but my money was debited.
Called the customer care and they sent the product except one (salsicyclic mask) worth 569 Rupee.
It’s been a month we are trying to call the customer service but they haven’t sent the product. They stopped answering calls from registered phone number. If we call from different phone they ask the query and put us on hold for hours. Irresponsible customer care. Please give my product or refund my money
