Ca final revalidation

Dear Friends,

I submitted Form for my CA final registration revalidation on 20-02-2017 but still after one month I did not received any confirmationn letter as I received at the time of my original CA final registration. In  this regard I want know whether ICAI send any registration revalidation letter to the student or not as Institute send the registration letter at the time of original CA Final Registration.

Thanks in Advance
