They have no where mention it's is not eligible it is not valid if customers use cool cash.
They are cheating the users.

We have not clubbed any offer, still the amount which they are suppose to receive after 14days from the time of delivery has not received. If customers are not eligible than they should have not got 1500₹ also. So that the customer could have cancel the order. But after 14 days customers can't return nor even they receive the cashback.

In my invoice it's mention wallet amount no offer.
When i talk to the customer care they don't have any answer so they are reporting the same line. Cool cash is consider as a offer but for offers we have a separate option.
Also at the payment page we get a pop if we select the payment stating we are not eligible for the offer.

So why in this case i didn't got the popup.
Also the cashback amount shown on the payment page was 2500₹

What i need to do now?
