Big Bazaar / Futurebazaar / Future Retail / Hometown — carrots

On 25.2.2019 i purchased 1.69 kg carrots. The display price was rs 9/.
I was billed rs 60.84.
On 26.2.2019, i purchased 0.74 kg. The display price was rs 10/.
The bill was rs 7.40.
On enquiry, i am told the price of carrots was rs 9/. Per 250 gm on 25.2.2019 and rs 10/. Per kg on 26.2.2019.
This is downright misleading and tantamount to cheating.
