Pepperfry — Manufacturing Defect product delivered

I bought Sofa from Pepperfry with Order No:[protected] on 11/4/2021 and product got delivered on 28/4/21. Just in 15 days we could see some big pins protruding out from the joining parts of sofa. Immediately i made a complaint to Pepperfry and their repair service person came and checked the product and told that it cannot be repaired as it is Manufacturing defect which needs to replaced by them. This feedback has been recorded on 2/6/2021.

From that day till now, i am not getting any response from them. Either they should refund the money or replace the product. But i have mailed, called their customer service so many times but till now there is no response except for automated mail stating that they will revert but till now no response. Actually i am so upset with their way of responding customers. I bought this through EMI and paying interest . But i am unable use the product and not getting any response. Request to support in this case.
