Smashing Commerce — received car polish instead of repellent

I have ordered uv mosquito repellent through smashing commerce website on jul 6th and order #156614. Today I have received parcel and when I opened it was car policy. Really shocking and when I checked the courier boy, he told to initiate return from the website. I have wrote a mail stating to return the product and process my refund. There no response till now. Please take appropriate action and help to get the refund.
