Probation/Confirmation letter

Dear Sir; Greeting Of the day I do have one concern and it is my personal official issue .I joined my current company in may 2016 and my confirmation was due in month of nov 16 and when I did follow up after waiting so long in month of January my reporting boss said we will extend for 3 months ideally i should have received probation extension letter in nov month itself but they didn’t give and in month of February when I approached again for confirmation letter they said we have processed for the same you will get shortly. Again after month when I approached they said we are busy in appraisal you will get along with increment letter in june but when I approached in this month my reporting boss said if we are not giving confirmation letter what is the indication you should understand I hesitantly said it means I must look for another job. he said right. Could you please highlight is it correct neither they issue any probation extension letter nor any confirmation and increment letter In my appointment letter it is mentioned that company can give once extension up to 3 month afterward they can relieve you after a notice of 1 month but nothing is done and since I am working in delhi regional office and my whole HR team is sitting in Head office Mumbai I confidently come to know through recruiter of HO that his boss asked him to search for another HR for regional office. I am too much worried how a company can play with me having such dirty intentions. I would be jobless and I am surprised it took them 1 year to judge me. What are the legal action I can take.pls suggest
