Flipkart — Used & soiled calculator sent in replacement- need 2nd time replacement

OD[protected]

I had ordered a CASIO Classwiz FX-991EX Scientific Calculator.
Originally I got an unit in decent condition, but only one problem, the cover was too loose -so I requested replacement.
--As per tracking details it came from Gurgaon.

The replacement I received has fingerprints & gunk on solar panel, and scratches on plastic. Also seal was broken inside the casio box (bubble wrap envelope seal inside it).
--But, the tracking details reveal that it came directly from Kolkata WB - which is my nearest city - instead of coming from Gurgaon again.

Therefore, it would appear to me that for replacements, Flipkart is sending people the returned products of other users.
Likely I got the returned product of some other person in my state (WB)- hence it originated from WB itself.

By now, 2 agents have informed me that 2nd time replacements are also possible if you contact customer support. Even when you are getting only refund option, you can contact us & we can book 2nd time replacement.

But for this product there appears to be some glitch & they told to try 2 days later if they can get the option then.

So I would request Flipkart team to kindly book a 2nd time replacement for the same, the seller was RetailNet (flipkart itself)- so it should be no problem.
I purchased this in sale & now the price has gone up.
