Samsung — Cashback fraud

I have purchased Samsung TV during Sep sale and I am eligible for cashback around 10k, which will be deposited with in 90 days, but it is more than 90 days and I am contacting Samsung for the same from 16th of Dec 2020, but there is no proper response from them, for single response I need have multiple follow-ups, I raised issue with all teh escalation channels available with Samsung support but still my issue is pending, Can you please take necessary action on Samsung India.
