Canara Bank — refund not issued

Address:

Kulathara Veedu, Kalady, Karamana po, Thiruvananthapuram, Kerala, 695002

I've ordered a jeans from amazon and since it was not good i returned it. After a while the message popped in saying that the refund has been issued but it was not reflecting in my bank account. I waited for 6-7 working days and then i contacted amazon customer care as well as my bank. Both the results were disappointing. I hope the refund will be made as early as possible.
