Had ordered a product of RS.2999 boat smartwatch in Amazon on[protected] & I returned this order due to different item received And on 1-7-2021 Amazon initiated the amount to my card but I still didn't get the money. Amazon sent this reference number 30005411831162183332463 and told me to fill charge dispute form but maharashtra gramin bank doesn't have such policy. So please kindly respond to this complaint it's very urgent.
