Company : Cinch IT Solutions LLP
CCB***/* “Shrusti” building, Angol Main Road, Tilakwadi, Belgaum-****** .

I was asked to resign on immediate basis without any notice period with a commitment of clearing the full and final settlement along with the pending salary for the month of February **** on the next salary data that is *th of April ****.
Now they have sent an email stating that the full and final settlement comprising of * months’ salary (February & March ****) will be done after ** days of my last working day (**st March ****) also I was promised a increment in the month of May **** of Rs.****/- but was not paid either.
I awaited thinking they would pay in bulk but that has not happened. They kept on postponing the appraisal dates again and again but never gave any increments.
I am attaching the email trail for the discussion with the HR department and the Owner for your referral.
Please help me to get my full and final settlement along with the arrears at the earliest as due to the Corona** lockdown it has become very difficult to manage the day to day expenses. Recently my mother got expired . and I am the only source of income for my family. In this tough time I am surviving my life badly. please help me out of this.
