AVA Merchandising & HDFC Cheats

AVA Merchandising sell products to customers on EMIs who hold an credit card, customers recieves the brouchers of products along with credit card statements, when you place an order over telephone the total value of the item blocked on your credit card and it will be billed in equated EMIs for the coming credit card bills, as the same way i placed an order with AVA on 11-08-2008, ordering the Blackberry mobile instrument for which value is indicated Rs.5990/ and i was told that it has to be paid in 6 EMIs, each EMI amounts to Rs.998/-.next day on 12-08-2008 i recieved a call from AVA stating that the product ordered by me was out of stock and if i wish i can order for another upgraded version of the Blackberry mobile phone which costs Rs.8450/ and the EMI would be Rs.1498/- per month, i gave my consent and confirmed the order, next day on 13-08-2008 i recieved a call again from AVA stating that an amount of Rs.8490/- was swiped from my credit card instead of Rs.8450/-, they said that it was by mistake and for that they are offering me a LOUIS wrist watch for which i have to pay Rs.490/-, as they have swiped already Rs.40/- from my credit card in extra to the first orderd product, they will swipe Rs.450/- more and will send me the LOUIS wrist watch, the person who took the order assured that both the products will be delivered with in 14 working days along with a free gift (ladies wrist watch Louis brand). After lapse of 20 days when i did not recieved either of the products i made several calls to the provided numbers to enquire about the order, either i was kept on hold for more than 30 min each time on an std call or i was assured that the product will be delivered to me within next week, when i was asking repeatedly about the time when it will be delivered or making requests for cancellation of the order the person who was online either keep me on hold for a longer perion or hung without proper response. Feeling disguised with the response of AVA i made request to cancel both the orders on 04-09-2008, the person who spoke to me said that the orders will be cancelled and the amount charged will be refunded to my credit card account with in a period of 14 days, but to my surprise the order no.2 whic is for the Louis wrist watch was delivered at my address on 12-09-2008 and the EMIs for both the orders were reflected in my credit card statement, when i try to call AVA with my regular number from which i was making calls to them it was either not being connected or if connected it was disconnected immidiatly after i speak out the order number regarding which i want to talk, it is a clear indication that they have barred those numbers, it is for sure as when i try to call the same number from another phone it was connected, i tried this several times and assured mself that they have some provision to barr the numbers which they dont like to answer.
Thus i searched the ways to complain about the matter, here i found this site and as i feel this is fraud and the AVA people are cheating public. these are the order numbers provided to me by the AVA. (1) 040045471 for Blackberry mobile (2) 160114717 for the Louis wrist watch.
Please make public aware how AVA cheating people.
