I ordered a burner( 3 burner) of pigeon - neptune brand, rectangular shape in oct-16 month to start my gas.
But i recieved the other brand - pigeon ( elegant ), that too oval shape.and defective also. As i cant take risk with gas.

and As i have to start gas i complain for the same and purchased another gas from near to my house . and complain for refund of my money.

Earlier they told that the amount will be refunded back, but know they are saying that they will replace the item

What should i do with two gas know.

I only need refund of my money.
