Ordered mi air purifier from flipkart sale. But the product is very pathetic and i cant able to use it. Due to their technical fault form flipkart i cant able to return the product. Now i m paying interest for that amount too paid through my credit card. No proper response from flipkart team also.
Not providing a proper solution too for my queries
