GSTR9 due date extended?

Date has been extended but as per the GST and CBIC helpline, they do not received any official confirmation on the same and according to them the last date of filing remains 30th June. Not sure what to do in this case. Can someone suggest?

Thanks for the revert, Monika! Yes waiting for Official notification on the same. Till then would you consider 30th June as the last date and will be filing return by 30th?
