Delhivery / Ssn Logistics — 3 times return and non delivery on prepaid order of muesli from true elements

Respected sir/ madam,
This complaint is against the courier company named delhivery and vendor true elements.
I ordered a food product worth inr 501 from trueelements.com on[protected] which was supposed to be delivered within a maximum of 10 days by latest delays and challenges. It has been 2 months undelivered now and when i track the order it shows returned back to seller for 3 consecutive times and keep on extending the delivery date to unacceptable time frames without my consent. They even dont make any contact or provide any information about my product and its delivery. I have already paid for the product and they never delivered. I have not been made a refund. It feels like i have been cheated, mislead and scammed. The product is of nutritional value and comprises a major part of my diet and well being which has been seriously hampered by the courier service delhivery mishandling. Please help me, i have shared screenshot of conversations with the vendor true elements and courier partner delhivery. I wish to oog a complaint for both
