Dear Mulubhai,
I do understand your disappointment. Our sellers cancel the transaction in rare situation, if they noticed that the product to be shipped is not up to the mark or not in a good condition.
In your case, international resller have procured your product in USA, but noticed that it was not as expected and hence refunded the transaction. Be rest assured, you will receive your amount soon.
Just like to inform you that it generally require 3-4 working days for refund to reflect in original mode of payment in case of Non-EMI transactions done via ICICI, CitiBank and HDFC Bank Credit cards. For the transactions done via other mode of payment and EMI may take maximum of 15 working days.
