Regarding Resign Letter

Dear Sir, I want know some query about my resignation. In time of joining some thing hidden by company hr side.I had join as a sr executive and 3.6 k is my yearly pkg and after joining we got only a letter from hr side and only 25 k 3 lac gross salary mentioned on it. in place of 3.6 ctc.No PF no leave from starting.no medical policy etc.Due to my medical related problem i was on leave for 10 days and he deduct my 10 days salary and asking about me medical documents and when i ask that ok i will give u medical certificate can u give me my 10 days salary so he says that this is no rule,So it was very surprising for me and i am very frustrating about and i give my resign letter to him.as per rule i gave him 1 month notice and he is refusing and begging me and i continue my job as usual.Now he is trying to mentally harresed to me and terminate my job.it is possible that i can take against a legal action against them. No any documents received from their side after 10 month only i have received appointment letter from there side. Thanks-Rohan
