Adidas — Money not received

Website:

www.adidas.co.in

I had ordered a size 9 shoe worth Rs 2000 a while back from Adidas online store. There was some size issue so I wanted to exchange the product but since there was no exchange option, I had to return them and then order a new piece. The product had been returned 15-16 days back and I had submitted by bank details 11 days back and yet I have not received any refund in my bank account. Kindly look into the problem as a refund should not take this long. Very poor services from a brand like Adidas.
