Provogue Shoes — Faulty shoes. Plz provide me replacement

Hi Team, On 08/16/13(11:52PM) I have brought Provogue shoes from Hypercity, malad(west). Brand: Provogue Cm NO- 2543 Reg:116 Store 01001 Till:8171 Size: 41 Color: Black M.R.P.: Rs.1150/- Paid mode: SBI Debit Card Shoes are just in Perfect condition but the it gives pain in side part of legs, My legs pains after wearing for more than 1 hours. Normally I buy size 41, After wearing once I am feeling that my legs pains because of shoes. I have contacted Mr. Bhaskar and Mr. Viren(hypercity mall staff mgrs) & They told brand will not taking it as a RTB. When i asked them to show me the proof about investigation done from brand side, they gave me the reason as it is confidential and can not share it. I have doubt that they had not approched to brand. Looking forward new pair of shoes in size 42. I like provogue & I trust on their staff fully. We look forward to your reply. Prashant
