Termination of an employee after filing a labor complaint for non-payment of dues

2 months back I filed a complaint to the labor because I wasn't getting off days.

My employer decided to give me two off days per month, but after two months he came back saying he is going to terminate me because all workers are complaining, and he going to compensate me.

Among the money calculated was all the overtime money, gratuity, pending salaries, dismissal amount (3 months' salary).

So we agreed on the amount to be paid, but when they presented the end of service entitlement form, the agreed amount wasn't stated and I refused to sign it. I went to the labor office and filed my complaint.

Now because I filed the complaint, the company has immediately stopped me from work. Is it right for them to stop me?

And was the amount I calculated the right one?
