ICICI Bank — cashback concern not resolved

Respected official,
I am a genuine customer of your esteemed bank service. I had made a transaction on the 7th of october 2015 on shopclues.com using your netbanking option expecting a 10% cash back as per the offer.

According to your biggest thank you sale hosted between 5th to the 10th of october 2015 by shopclues, i was supposed to receive a 10% cashback since i had used my icici bank net banking account for payment. I have been constantly following up regarding this issue but haven't got a proper resolution till now. Please credit my rs.2794 cash back immediately.

For your reference, i am providing all the necessary details:
Shopclues order no.:70502827
Transaction amount: rs.27949.00
Transaction date:7th october, 2015
Icici bank account no.:[protected]
I have even attached a few pics which may be helpful in the investigation process.
