No response to complaint

I have recently bought a pair of shoes at Identity, Canal Walk as I was the best man in my brother's wedding. The store consultant (after checking the shoes Infront of me) managed to give me two wrong shoes. I opened the box a hour before the wedding only to find out that I had to left footed shoes. I had no other choice then to borrow one of the guest shoes (someone I don't know). I have logged a complain with their complaints department but until today, I have not received any feedback.
