No! They had not yet received any notice from ROC


But ROC had issued a Public Notice. Which says:

  And the name of company is included in this list. 

Thanks!
How much time do they have before ROC itself strike-off the company? And as the company is doing the business since 2011 and is defaulted since then what about penalties, fine or imprisionment.

As the Public Notice on MCA21 website is Dated. 31.03.2017 so the expiry date was 30th April. And now 35+ days had been elapsed after it. And as per rule the First AGM Should have been within 18 Months of formation of the company. 5 years had been passed without any AGM. Is there any chance of imprisionment or heavy fine for the Directors.
