Tata Consultancy Services — Experience/Service letter not received

Address:

TCS bangalore

I submitted my resignation on Sep 10. I got my initial release letter and FFS on Oct 5. I am yet to receive my Service/Experience letter from TCS. When I mailed HR they asked for a ID card handed over proof from admin. I provided that as well. They said it will be processed in 7 working days. But it had been 1 month so far still I didn't get my letters. I even raised ticket in TCS alumni portal but no luck even after 4 days. That ticket is still in open status.
I am in need of my Experience letter urgently. Kindly help me on this.

My employee id is 976466
