Flipkart — I am complaining about order placed on magic bullet mixer grinder in flipkart

Address:	Chennai, Tamil Nadu, 600114
Website:	Flipkart

2 weeks back i ordered for magic bullet mixer grinder (Price rs.2198/-)
After some days they supplied the package and i paid the money cod. Upon opening i found the product is amazing bullet a similar product with different brand, priced around rs.400/- less by same flipkart. I requested for return and only option shown to me was a refund. I gave all particulars. Later some customer care person called and told me to hand over the product first then i will be getting the moneys within 5 working days, which i did not accepted. Then for every 2 hrs they call me and each time they are repeating same thing which was not acceptable to me. I was told that the product i sought was out of order. I asked in that case why they have not either cancelled the order or inform me for which no answer. Then after 3 days again i got a mail to re request for replacement as there is stock.

I did so and today they supplied again the same amazing bullet and took the earlier delivered product. Again i requested for refund!
Ame procedure follows now — they call every 2 hours since morning.

I want flipkart to first refund my money then take back the product. Or let them hand over me in cash and take their wrongly delivered product. [ i paid as cod - cash on delivery. Let them do codb - cash on delivery back]
