Paytm Mobile Solutions — misbranding

Website:

On the landing page of iphone, cashback mentioned as 7250.
And once i click on the product, the cashback mentioned in offers section is 6250. I was about to order the handset having faith on paytm, but at the last moment when i saw the cashback is reduced it shattered the trust.
1000 wont make much of a difference but trust and faith on paytm is gone by this act.
This is clear case of misbranding and fooling the consumer.
Attaching screenshots with the product in question highlighted in red coloured box.
Waiting for an explanation!
