Zara — Refund not initiated by Zara

Hi,

I raised a return request to zara on 9 December for 5 items and the request was approved on 10 December and they scheduled a pickup for the same. The items were picked up via Ecom express AWB number [protected] on 10 December at 9:23 am and delivered to the Zara warehouse on 14 December. But Zara is denying that they have received the products and are not giving me the refund. I have screenshots and proof that items have been delivered to the zara warehouse at Bilaspur on 14 December.

Can you please suggest a way to file a consumer case against zara? Or any other way in which I can get my refund back? Because this is absolute cheating and zara anyway has an extremely bad customer support network. Not able to voice and escalate my concern. Please help out.

Regards,
Aishwarya
