www.Indiaplaza. In — Non-delivery of mobile

I ordered Sony Ericsson mobile phone Xperia neo-V with indiaplaza.in vide order number IN[protected]. The order was placed after confirming stock with Mr Kumar Velu telephonically on 18th November ( Friday ) & paid online through ICICI bank credit card. On 19th November, ICICI bank authorised their account for this amount at 11:18:06 AM.
Their shipment time is 2 ~ 4 days but yet I have not received the product. My repeated calls & Ms Shashikala ( team leader ) confirmed by email that the product was shipped through First Flight courier # F11257257. When I contacted First Flight courier, I was shocked to hear that such docket number does not exist.
They are lying to me continuously. Now I am worried about the money they have already debited to my account.
Please help !
