Tata Consultancy Services — tcs alumni portal does not open tickets

Address:

Kolkata, West Bengal, 700156

Hi,
I left tcs in nov 16, 2018. I have initiated pf transfer process in the alumni portal, but they have not started working on my ticket even after a month. The status is open. Meanwhile i am receiving mails from them if i dont complete the process they might donate my balance, when it is them that are not responding.
It is been almost 2 weeks i opened another ticket. That too is unresolved. They dont have any other way of communication such as mail or phone number where i can reach them. Please help.
