Consumer Redressal

I am Pranab Saloi from Mumbai. I had placed an order to purchase one Samsung Galaxy S4 Mini mobile from online shopping site www.retailbunny.com on 04 Dec 13, costing me Rs 21266.00. It has been more than 14 days but I have not received the item. I have repeatedly called the customer care call centre no. 9650787333 for more than 20 times but everytime they say that all executives are busy and that they would get back to me but they have never responded to my calls. I have also sent more than 5 emails but again no response. On their site i.e www.retailbunny.com where I have an account but whenever I try to track my order status, it says I have not placed any orders with them, however I have the receipt of the money that I have paid to them. Pls help me.
