Tata Consultancy Services — non issue of service certificate after full and final settlement

My name is gaurav kumar. My tcs employee id was 755417. I have resigned from the organization on 10th july 2019. It has been 43 days since i resigned. I have received release letter and full and final settlement letter in july itself. When i asked for service certificate i am being asked to pay the amount again. I am studying in a college now and this is very difficult for me to comprehend why even after getting the full and final settlement letter; i am being asked to pay again. All other associates who have resigned from tcs to join the same college are not asked to pay again.in ffs it is clearly mentioned that shortfall amount has been deducted and i have been issued full and final settlement. Why am i being asked to pay the amount again? What is the logic of full and final settlement then, if one has to pay even after ffs?? I have raised several tickets on alumni portal but there has not been any response except acknowledgement in last 13 days. There is no other way to contact tcs than to raise a ticket, where i am not getting any response.
