Cognizant Technology Solutions — Not received relieving letter and final settlement

Address: Chennai

My last working day with cognizant on May 31, 2021. But I am yet to receive my documents like relieving and experience letter and also nobody replies from the clearance team. I have sent many mails to exit help desk India but they are not bothered about my problem. I am unemployed for more than a month now. I am the only one earning at the moment from my house but they can't even understand what I am going through eventhough I am dropping a mail everyday
