Bata India Ltd — Wrong Size shoes Supplied

I placed an order of BATA Shoes (FRANKLIN, order number[protected] online on 15th Aug 2012 @21:49:21hr. I was surprised to receive the two different shoes are of different sizes - right one is "9" and the left one is "8". It is really hard to believe that a world class company is doing business in such a poor manner specially when the two different sizes are marked and highlighted on the bottom of each shoes. I had made the complain to their customer care email id (customer.[protected]@bata.co.in) on 21st August and also called their customer care number[protected] several time, but no solution was provided. They even did not response to my email. Please help.
