Reebok Store Delhi Rajiv Chawk — Poor customer service and replacement

I have purchased a Reebok shoe from Reebok store(A.P.Retail), Mc Donalds Tower, G.S.Road, Bhangagarh, Guwahati, Assam on 05/02/2008.
But my utter surprises, the pasting of the shoe was out within 2 days.So I contacted the concerned store on 09/02/2008.They note down the complain and assured me that my shoe will be replaced by 29/02/2008.
After that I contacted the concerned store on 29/02/2008, then they simply told me that my shoe was sent to the Head Office and I will be able to get it within 2-3 days.
Then on 06/03/2008, they told me over phone that I will be given the shoe on or before 13/03/2008.
I contacted them once again on 13/03/2008, but they informed me that it will take another 2-3 days.
Next on17/03/2008, I went to the store to enquire about the shoe, but this time also they simply refuse to give me the shoe, citing that there is no response from the Head Office.
Now, I am surprised to see how Reebok claims that their customer services are good .OF COURSE THEY ARE GOOD ENOUGH TO CHEAT COMMON CUSTOMER.
