Hello sir/ madam,

My name is rashmi raghavendra (Employee id: 830703). I joined infosys on 26 april 2016 and resigned on 01 may 2016. I served my notice period anf my last working day was 31 may 2016.
I received my relieving letter, but from june end the company is harassing me that i've to pay 25, 000 because i didn't serve notice period. Also every time they are coming with new reason.
Firstly they told that salary was paid to me so i'd to repay the salary. When i proved that how can salary be paid when my bank details was not update in the salary slip sent by them only.
Now they're telling the system is reflecting lop & the register is not showing my entries.
All my question had i not served my notice period how can i receive my relieving letter.
This is really a mental torture. Kindly help.

Regards
Rashmi
