Amazon — return money

Address:	Vadodara, Gujarat
Website:	amazon

I purchased a adiso mens synthetic leather stylish sneaker shoe rs 489 from amazon on 15 aug 2018 and done full payment by debit card but i can return the item to amazon on 21 aug 18 and now amazon saying that refund has been send to bank on 22 aug 18. So contact customer service and the file charged dispute. They had given me a refund reference number[protected]. But customer service is saying they can file nothing like charge dispute and can only check if money came to your account or not. Don't know what to do
