Smashing Commerce — why so late for refund

Address:

Hyderabad, Andhra Pradesh, 500002

After watching the add on facebook, i ordered smashing commerce's pest control/repellent product which recently claimed to be an effective pest repellent product. However on receiving the product today following things i have noticed about it which really really upset me and made me realized that i have been made a big fool:

1) the product looks completely different from what was shown in their ad. The one i received looks like a cheap product or kids toy which just makes a buzzing annoying noise on connecting to plug.

2) is there any way to get the refund?

I have paid 480 for it however it seems only 50... Cheap product... They are cheating customers the customer service manager is not picking up the call nor responding the call. It is very annoying.
