Smashing Commerce — zoom phone lens

Address: 247-F LANE 2 PHASE 2 JANAPRIYANAGAR, MIYAPUR, Hyderabad, Andhra Pradesh, 500049

Dear sir,
I ordered zoom lense to fit to mobile phone as per advertisement by smashing commerce pvt ltd and priced at @499 / and i got it delivered at today only thru xpress bees hyderabad by cod
To my austonishment it's of no use. It's not working at all. There is instructions manual to show how it operates.
There is one ankita, business success manager not at all responding thru given contact no.

As per return policy pl take it back and return my money asap

It's happening to be cheating even by looking at price.
In amazon same lense costing rs 199/

And these cheaters charge 499/

Pl return money
