Lera Technologies — Not responding for EX-EMPLOYEE

I am ex-employee of Lera technology . Requesting for skillset from Lera for more than a month which is mandatory for PR process. HR to whom i have mailed is not all responding for my mails. Also mailed to [protected]@lera.us . No response yet. The company didn't provide me the final settlement also. I have requested many times and ignored asking for it . Atleast now, as a responsible concern should provide the requested letter for the employees. HR is responding to my registered personal mail but when i mailed from my another mail ID, they are responding. But after realising its me, They stopped responding to my mail.
