Fonezone — refund not provided

I purchased a Nokia 107 phone form Fonezone. The price was Rs-1234. After placing the order, I realised that the phone was Refurbished. So I called their customer care and asked to cancel the order. They said, even its refurbished, it will be almost new. So I didn't cancel the order. But the received phone (116th December 2018) was very old and have many issues. So I contacted customer care and they asked to return it back. I sent the item on 17th December 2018. I got a call from Fonezone saying that they got the returned phone. And from that day, I am waiting for the refund. While writing this, the date is 4th January 2019. Still I didn't get the refund. Customer care of Fonezone is not even giving a proper reply
