Sir-If your furnishing is correct Your CA might not submit the details to your AO at the time of hrg or he had not attended IR hrg at all.
The option to you are:
01 Call on AO directly - none can ask you/bar you to appear before him.. While going to Income Tax office go with your original PAN card or Deed of partnership to prove your identity and inform to AO the happenings
Exparti order cannot be made when the details are furnished to AO At thebest he can reject it
Hence check your CA
02 can file Appeal before CIT {A} and there is every chance to win over.
With best wishes
