Smashing Commerce Pvt Ltd — defective phone holder

Address: Panchkula, Gautam Buddh Nagar, Uttar Pradesh, 201308

I purchase phone holder from bestphonemount.in via Facebook. The quality of phoneholder is very poor. On the box trader name is shown as Smashing Commerce Pvt Ltd. There is no working phone number. I am feeling cheated by this low quality product. I paid 500 RS for this useless product . Its cost is not more than 10 RS. Pls let me know to refund the amount for this cheap product.
