Ekart Logistics — Refund amount

I had recieved an parcel on 19th december which i havnt ordered, still delivery boy forced me to recieve it as it was on my name and address, after opening parcel, some old and torn clothes was inside it. Within half an hour, i returned it to EKARTs OFFICE, situated at OMKAR NAGAR, NAGPUR. They had collected that parcel and commited a refun as early as possible. As i had paid COD through GPAY, they said it will take 4 days to refund the amount. After that from 23/12/2022, im calling them and visited in office too, stilll amount is not credited/ refund in my account. Everytime they said, we are trying and by tomorrow evening, your money will be refunded, today on 11th of jan 2023, I didnt gety my money.
