www.tradus.com — Non-receipt/ delay of refund by the website

Address:

Ahmedabad, Gujarat

My order No. 8943738_01 dated 11-may-2013, for "Envie 4 x AA 2100mAh Ni-Mh Rechargeable Batteries" was cancelled by the website itself on 18-may-2013.
After that (on 23-may-2013), the website showed:- "Your order 8943738_01 has been refunded. The funds will be transferred in your account within 3-4 WEEKS (Depending on your bank)".
If the refund has been made by the website, it should have reached immediately. I want them to provide me the method (cheque/DD/PO etc) of refund adopted by you which takes 3-4 WEEKS to be credited to account. Also they should provide me the reference number for that refund you have processed. It has been more than 13 days since i had made payment and more than 5 days since cancellation.
