Gonoise.com — Different product received

I have ordered noisefit evolve 3 vintage brown on 28th march, received parcel on 30th night.. Next day opened parcel pack and saw intact product packet of vintage brown. Next day when i opened product packet to charge the watch, to my shock it was a black watch. Its cheating. They sent packet of brown and inside different watch. Since that day till today i am contacting their customer care and they are harrasing by asking for pics videos and what not. Always after sending every thing they mail saying sent to concerned department. When mistake is on their part, why harrasing me . I have paid gonoise and i must get the product for which i have made payment. They are not replacing it.
