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 tomorrow thru xpress bees delhi by cod
To my austonishment it's of no use. It's not working at all. There is no any instructions manual to show how it operates.

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

It's happening to be cheating even by looking at price.
