Tskhadi — Refund amount not received

I bought saree for Rs. 2200, it was torn from blouse. We requested return which were attended after 8 days when I wrote some harsh words to them. On 25th September they picked return by Delhivery. After lot of reminders from last 10 days, they are not responding to my call, WhatsApp and mail. As per refund policy I provided proof of damage and they have to return me Rs. 2080, after deduction of courier charges.
Still on 12 Dec. 2020 I m not received refund.
