[Resolved]  Nilkamal — Cashback Offer Not Received

I bought products from Nilkamal and have received Cashback coupons. These coupons are to provide Rs.100 cashback once claimed (within 48hrs). I have got four coupons which I claimed them on the 6th of June 2022. And today is 16th June and not a single Rupee has been received.
I have mailed them and they simply stated that it will be processed very soon. 3 days gone and still no cashback.
It is not even about the money, its only 400 rupees. But being a valuable customer to the brand and getting Scammed with such Fraud offers just makes me really MAD.
I cannot understand why such a reputable brand like Nilkamal would do such a Fraudulent act just to attract customers.
