ICICI Bank — ICICI Credit Card - Cashback Not Received

I had purchased a TVS Jupiter Scooty from Arvind TVS Motors Agra(UP) on date 31/01/2021 amount of Rs 83833 (Sum of two transaction) using ICICI Bank Credit Card. There was cashback offer going on at that time using ICICI Credit Card. The offer stated that within 90 days the cashback will be credited in the bank account but it's already 250 days yet I have not received the cashback and ICICI Customer Care helpline are not providing sufficient help.
If its a fraud, I will never use ICICI Bank Credit Cards
