Hi,
I hope this email finds you well!
I purchased a Haier 425litre refrigerator from Reliance digital online on 14 July 2024. Order No: RDF64311148. The product was delivered on 16th July and when it was installed by Reliance digital engineer it was found to eb faulty. A return and refund was initiated and the product was picked up from my residence (Savoye A 102, Ambika La Parisian, Mohali, Sector 66B Punjab) on 21 July 2024. Its been 10 days since the product was picked up from my but I am yet to receive refund. When I reached out to customer care they refused to give any detail by what date I will get the refund. Please help!
