Address:

No:23,7th Street,teeds garden,sembiam,per am bur, Chennai, Tamil Nadu, 600011

My name is j thasneem nehreen and i had ordered vivo v15 pro product of rs.13, 740 in amazon on 29/09/2019 and after 01/10/2019 i returned this order due to personal reason. And on 02/10/2019
Amazon initiated the amount to my card but i still didn't get the money. Amazon sent this reference number:30005492769272210839798 and told me to fill charge dispute form but indian bank doesn't have such policy. So
Please kindly respond to this complaint it's very urgent. My card number is [protected]
