Zipker Online Services — return n refund of product

I have ordered a product bt being dissatisfied with the product i wanted to return the product but no confirmation regarding return has been received by me.. Its been 5-6 days but i haven't got any return confirmation yet.. So i called the customer care executive.. Neither the customer care number executive is answering my calls.. Nor any of the other nmber given is available for customer service.. It's very dissatisfying..
