Servind Notice period

Respected Sirs / Madam, For the past 6 years I have been working with a Company. The Company has not served me any Appointment Letter. The Standing Orders of the Company is yet to be approved by the Officials. On the 7th of Oct'17, I had sent by email me resignation letter stating that since the Company has not provided me with an Appointment letter and neither the Standing Orders are published, therefore I am not bound to serve any notice period. After that on the 16th of Oct'17 I again sent one appology email and on the 11th of Nov'17 I was supposed to hand over all the statutory files maintained by me. Unfortunately on the same day we all became emotional and the process was not completed. Meanwhile after speaking to our Management and as per their advice I have sent them an email stating the reasons for sending my resignation letter. Even after that I tried to get in touch several times with the management people over the phone to know their decision but my calls were not answered. Now I want to leave immediately, so please advice.
