We have provided good treatment in private hospital but they are tried their level best to save his finger but unable to attach that we have reported to ESIC in form 12 online . But not reported to factories. What to do now some people are saying it should be reported in factories and some saying by reporting factories it'll lead to other legal issues which is right I'm in confusion what to do now. Help me any one. And also tell me how to get refund the treatment expenditure through ESIC.
