Shopping. Rediff.com — product not delivered as per my order

Address:

Maharashtra

I had ordered a product from shopping.rediff , a BLUE LED watch (http://shopping.rediff.com/product/2013-blue-led-display-cum-silver-bracelet-watch/11534300?sc_cid=search_...⇄ which is of 349 INR
and had clearly mentioned there that I want it delivered to me on 17th march 2013 , yet they delivered it to me the next day... anyways thats not big issue...
the thing is they sent me a cheaper version of the watch thats available on their site... a RED LED watch which is of 299 INR ...
also when i was watching a product , I got a call from some representative of their and told me that if I make Cash on Delivery for that product then il be getting a certain discount... I will get it at only 299INR+ shipping charges... so i agreed and placed my order or else i prefer payment through a debit card...
so in short my order was of BLUE LED braclet watch and that was as a gift which was to be delivered to me on 17th march 2013 , but they got it delivered to me on the very next day but a cheaper RED LED watch.
I tried contacting their customer helpline number for 2days ([protected]) but it always says that all personnel are busy at this moment, so then i filed a complaint through email , COMPLAINT NO.[protected]
but all they keep on saying is that they have shipped the product as per the order...
well i think that the order was made by me so i would be having a better knowledge of the product ordered and not them...
please help me...i feel CHEATED..
