Central Board Of Secondary Education [CBSE] — Termination and post termination

Greetings
My name is Md Bakhtiar Alam and I have been serving as an English Teacher at Open Minds A Birla School Danapur, Bihar ( Affiliation No 330503 ) since 6/11/2019. On the 30th of June, 2021, I got a whats app message stating that my service as an English Teacher has been terminated with immediate effect.I was shocked to see that as there was no prior notice neither any prior negotiation. I was asked to submit the books and the other records and clear my dues. I went to the school at submitted the books and all but so far neither my salary of June they have dispensed nor the three months salary which is paid to the teacher if he is terminated without any information. Neither the principal is receiving my call nor she is replying to my whats app messages. I feel very embarrassed. Worth to mention, there has been a deduction of 30% salary since April 2020. It was assured that these amounts will be reverted once the lockdown gets over.
At this juncture of time, its not possible for me to get any job.
Therefore, I request you earnestly to look into this matter and do the needful as per the norms of CBSE.
Thanking you
Md Bakhtiar Alam
