I resigned from immediate effect from an organisation after joining on 3rd day. On day1 of joining i did not login through system since my laptop was not configured.I just attended induction trainings through microsoft teams app the links for which were shared on what's app by HR person.on day2 I took holiday and on 3 rd day i resigned and even when I resigned I did not had the login id and pssd to login into thier systems so I resigned by sending an email through personal mail id.
In non disclosure agreement which they provide notice period is mentioned as 3 months which is not possible for me to serve. The non disclosure agreement is signed through DocuSign which is valid or not I don't have idea.
Can they legally trouble since I joined on day1 but i did not have access to login into thier systems and the day I resigned I still did not had access. Also I have their laptop with me and the joining bonus sent in my account which I am ready to return.
