Rediff Online Shopping/ojjas Enterprises — Pathetic customer service

I bought a portable sewing machine online as a gift to my mother from Rediff online shopping on 10 October - Order number-4933225. On 15th October i received a hand sewing machine, which was nothing more than a 'STAPLER with a thread.' I tried calling Ojjas Enterprises who were the sellers for the product, but it is busy 24/7. I then posted a complaint on Rediff, Vineesh Jain responded, asking me to courier the product. Which i did and sent an email to rediff confirming the same. But till now I haven't got any response whatsoever. I am thoroughly disgusted with the customer service. Inspite of 5 chasers, there was no response at all. I want everyone to be aware of the service of Rediff Online Shopping cheating tatics.
