[Resolved]  Amazon India — amazon pay cashback not paid

I made a recharge for my jio number of rs399 and was eligible for rs99 cashback offer. The company assured it will be credited in 7 days but 13 days have passed and no cashback has been recieved yet.
I called their customer service thrice and everytime to wait for 24hr but no response or action was taken on their part. The way they were talking was also not polite and were very arrogant.
These fake assurances and wrong offer should fall under false advertising and customer harrasment.
For this non payment i have to delay my other purchases which was a opportunity cost to me.
