Website:	Canara bank

Dear sir
My account no[protected]
I order a product on amazon on 19th of this month using my canara bank debit card but the amount of 736.25 is deducted twice from my account then i cancle the order and i asked then for refund. As per their confirmation refund was initiated on 19th of this month. Still it was not reflected in my account. They had provided the refund reference number as #519798 & #929826. 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.
