Wipro — EMP NO. 20209398 Need to understand the policy about joining bonus

I am an ex employee of Wipro technologies and my EMP NO. was 20209398.

I joined Wipro on 31st Mar 2021 and left the organization on 29th April 2022 which has completed more than 1 year.
In the offer letter it is clearly mentioned like " Should you separate from services at Wipro before completion of one year from the date of joining, irrespective of the reasons for separation, you will be liable to pay back to Wipro the entire gross amount paid as Joining Bonus. "

As per Wipro Offer letter I should not return the joining bonus as i have completed more than one year. But unfortunately it's showing in my full and final settlement.

I chased to both fnfsupport.[protected]@wipro.com and radhika.[protected]@wipro.com (Radhika is my point of contact for final settlement process) daily but there is not a single update from their side.

I don't know to whom i will contact so that i will get the clarity for the same.
Multiple incident i have raised through ALUMNI PORTAL But below response i got from portal.

Resolution code = Solved (Permanently) Resolution notes = HI, For quires relating to final settlement pls drop a mail to Kindly drop a mail
to fnfsupport.[protected]@wipro.com. Regards hrss team.

Please advise what will be resolution step for the same.
Kindly assist me on priority.
