Tata Consultancy Services — Tax Query not yet resolved

My emp ID is 1561999. This is regarding my FFS settlement, I was on deputation in Germany and to serve last 45 days notice period I went to India as per company policy. For these 45 days TCS asked me to pay approximately 1.8 Lacs INR as a Tax amount to clear my FFS. I was in urgent need of FFS hence I paid the requested amount.
After few weeks of FFS, I raised a Alumni ticket (#1064718) asking for clarification but now it is more than 2 months and no one is willing to provide me the justification. Simply TCS corporate HR is responding to my personal email mentioning that they are discussing the matter internally and come back to me. I have received around 10 emails from corporate HR asking for more time. I suspect some scam/fraud/mistake has happened here hence no one is willing to answer.
Requesting to please have a look. Let me know if you need more info.
