Consumer Redressal

Hi my name is rick mitra , I recently bought a tissot watch form snapdeal . com . After getting the delivery of that product I went a tissot showroom in kolkata but they said the product is fake n completely duplicate copy . I mail snapdeal at least 20 times they ask different images , still I send all possible pictures . But again they ask for another picture but I already send all possible pictures. I think they are not taking this seriously and trying to avoid me . Please do take some step.
