Smashing Commerce — product totally different that shown on display site

I had ordered a pest repellent from smashing commerce on 12thof august that i got it today on 15th of august. When i opened it i was totally shocked because it was not that similar product that i ordered and displays on their site. When i checked it i come to know that this one is a totally useless product. This pest repellent is too noisy and not pleasant at all and even creates the problem of headache. I had paid 480 rupees for this fake product even its worth not more than 30 rupees. When i am calling them they are not receiving calls. I just wanted to return that fake product and wanted my money back. This is fake company that cheated me. I hope you will take my complaint in action..
