Cognizant Technology Solutions — Full and final settlement not received

Hi I have being facing issue where my full and final settlement was not settled to me for more than 5 months.

I have resigned on June 30th 2020 and submitted my assets by July 17th due to the Covid-19.
My last working date is June 30th 2020.

I have followed up with Exit Helpdesk for more than 25times and all went in vain where all the tickets are closed.

I need my full and final settlement with date confirmation as I need to take care of my personal issues.
