Central Board Of Secondary Education [CBSE] — Regarding salery

I am teaching in Don Bosco Sr Secondary school Gorakhpur uttar pradesh since last 2 years, during the lockdown period I took a online classes continuously but salery is not given by school continously, they give only 3 month salery between April to September and the salery amount is 50% of the total salery, so I request to cbse to take a proper action on the school for recovery of my remaining salery amount, I taught in October also upto 19 October but after that I left the school because I have much requirement of salery and they don't transact the salery. Please consider this complain.
