Form inc-22a

My client has filed ADT 1, 2 years ago with wrong appointment period, i.e, instead of entering 01/04/2016 to 31/03/2021 client wrongly entered as 01/04/2016 to 31/03/2017 but the client mentioned the term as 5 years only in the form. 

Because of this while filing INC-22A  it is not filing and further showing the error that "auditor appointment period should not be less than 31/03/2019".

I have raised my issue with mca21 helpdesk but no reply as on today

kindly help me
