Tata Consultancy Services — TCS Alumni Portal Login Issue Since Aug'22

My last working day with TCS was on 22nd Aug'22. After that I tried to access TCS Alumni portal but was unable too. Registered manually and I received an email (on my personal email ID) that the TCS team is looking into the registered and the account will be activated once it is approved by the TCS team. Since then, the account is in the same state. I have raised multiple tickets for my access issue. I only received one response that I need to re-register. But the portal is not allowing me too as my personal email ID already exists in the database (somehow). As of today also, I'm getting invalid ID error when trying to login into TCS alumni portal. My ticket no. related to this issue are 932246, 927275. Please look into it and resolve it ASAP.
