Flipkart — refused to change the pendrive even we have bill and warranty

Address:

Rajkot, Gujarat

we have purchased a sandisk pendrive from flipcart.but when we checked it..it cant be detected from any computer.so we have requested the company to solve our problem. Now no one is giving us proper solution of the problem.we have warranty period and bill also.so please kindly change it otherwise strict actions may be taken by us and even if the warranty period will out the flipcart will be responsible for this and they have to change the item as soon as possible and if the problem is not solved then we will go for"grahak surksha".
