Address:

Shaheed baba Deep Singh nagar St.no.2, Muktsar, Punjab, 152026

My name is satinder singh and i had ordered boat rockers 400 headphones of rs.999 and boat bass heads 100 of rs.349 in amazon on october1, 2019 but next day i had cancelled this order due to some personal reasons. Amazon initiated the amount in my card but still i don't get the money in my bank account. Amazon sent me this reference number[protected] and told me to fill charge dispute form but bank manager said to complaint online. So, kindly respond to this complaint. It is very urgent. Thanks sir.
