Zeraki Jwell — Bangles order not exchanged, return delivered but no refund of Rs 704

I ordered 3 bangles from Zeraki Marketing on 1 Oct for Rs 624. They sent wrong size. On 10 Oct I paid Rs 80 extra for exchange as they asked.

I returned the product via courier AWB [protected] which shows delivered to them. But they did not send exchange nor refund.

I have raised NPCI dispute via Paytm for Rs 704. Seller is not replying on Instagram and WhatsApp.

I want full refund of Rs 704.

Date of transaction: 1 Oct and 10 Oct
Amount: Rs 704
Payment method: UPI via Paytm
