I purchased a product on amazon on 10th of this month using my canara bank debit card and return the item but a refund was not received. As per their confirmation refund was initiated on 21 th of this month maximum time frame was 5 days. Still it was not reflected in my account. They had provided the refund reference number as 280781. I had contacted your customer service number they is no proper response hence i mail you. Please check and confirm the status if your response was worst in mail too i'm going to file in banking ombudsman.
