HCL Technologies — Harassment

Address:

House no . 3157/ A, Sector -3 , Housing board colony

Hy,
My name is Nikhil and i am an employee of HCL Technologies Ltd Noida .
I have been working with HCL since 2nd Nov 2021 and before signing the offer letter it was told to me by HR of HCL that My Inhand salary will be Rs 31, 618 per month after all deductions. Due to this i had an offer of 32000 per month in some other company which i denied .But when the salary came for Nov month the salary i am entitled to get is 30000 something.
On being asked about this HR told that she is very sorry and she is a new employee so she forgot to inform the Deductions for which i do have call recordings also.
Now when i told HCL management about this they have been neglecting this issue since today and no one is ready to provide any resolution. Everyone is passing the issue from one plate to another plate and in between these months i was ill for few days for which i provided medical also but they threatened me.to attend the classes and bring laptop and they stopped approving my attendance.
Now i am tired asking them multiple times about this issue but no one is able to come with the solution. Its completely Harassment HCL is doing with its employee and i need justice for the same .
Hoping to get justice from here.
