Cognizant — Experience Letter - no response from CTS

Hi Team,

I'm the ex employee of CTS. I tried to get my experience letter and sent the email with the Job description to [protected]@cognizant.com. It is more than 2 weeks and there is no response from them inspite of me asking for the status multiple time. I mean literally no response at all. I don't even know whether they are operating.
