ZEPTO - INALSA FOOD PROCESSOR DELIVERED DEFECTIVE TWICE

I purchased Inalsa Food Processor from Zepto using gift card money on **.**.**** which was found damaged and since the company does not have another piece it was returned and money was credited back to Zepto Account. Next Day the Inalsa Food Processor was again available in the Zepto Store and so i reorder it, but to my surprise, the same defective piece i returned yesterday was again sent to me, which i rejected on door steps and money was again refunded to the zepto account.
After that i requested the Zepto Account that since they were unable to deliver the required item i want Zepto Account money transferred to my Bank Account. Even after long chats they refused to transfer the money to my bank stating that as per Zepto Policy Gift Card Money Cannot be transferred to bank account. I understand that in general gift card money is not transferable to individual bank account, but in my case they are unable to deliver me required item and now blocking my money they made me unable to purchase it from somewhere else. They have given be lost of mental agony by their continuous nagging behavior.
I request you to please look into the matter and make the zepto to deliver me new Inalsa Food Processor or to transfer the zepto account money to my bank account.
