Clarks — shoe bite

I purchased unstructured clarks shoes on 7th august and started using it only to find that it started biting my both little toes very badly and it is swollen, mr chetan the shop keeper saw the same and apologized for the same. I am expecting change in the product and nothing less. Very disappointed with the product and the service.
Please oblige and do the needful. Expecting a positive response from you.
