Dear Sir/Madam,

I was sent call back request on flipkart website portal. they called me with number [protected], I told them my problem regarding product availability pincode wise, and that product (Sennheiser cx180 headset wired) sell by BUZZINDIA.
I ask to flipkart customer care for seller's (BUZZINDIA) contact number but they provide me wrong number.
I called that number, front person said it's not a buzzindia's number and i'll register complaint against you if you call me again.

it means that flipkart having fraud seller and they accept it.
