I have ordered a cantabil reversible jacket worth RS -1727 the product has been delivered on 27 November 2023 in which i have received a black tshirt then i filled a complaint in Amazon then after 2-3 days after verification i got a call from Amazon specialist team in which they were saying i have checked your complaint and i found that the mistake was from our end then the product qas picked up successfully . After pickup i got a message in which Amazon was saying we will initiate the refund after the item reaches our warehouse .
