Termination on probation

1. I joined Air Force School on 19th April 2017 through a legitimate process as Permanent Teacher with 1 year probation which may be extended for another two terms ,6 months each ,in case of unsatisfaction. 2. But, on 15th Feb2018 , the authority circulated an office order inviting application against my post on contract basis for 2018-19 session for internal teachers. 3. When I discussed the matter with the authority, they asked me to apply for the post and after two days ,they issue a counseling letter mentioning some minor mistakes. Afterthat , on 15th March,2018, they issued a termination letter mentioning, your service may be terminated on 18th April 2018 by writing ,"your teaching is not as per our desire". Finally , they gave an advertisemen in a daily newspaper, where applications are invited against my post mentioning "permanemt basis on probation". 4. I am MA, B.Ed. PGDIT and have more than 10 years teaching experience. I have passed their equal opportunity test consisting written test, demo class and viva. Now Sir what will I do. It will become a matter of social prestige and financial hindrance for my family at 41 yrs of age. Please guide me in this line, altgough I have requested them several times for a chance. They have no answer of my questions.
