No, they should have responded back by now. You say that they were planning to open a case 1 month ago. Do you know if they executed that plan? Better to consult your attorney and ask him to get on top of this case.
The online status is still Initial Review or Acceptance?
I am in the same boat this year as on 3rd March 2017. My case got picked up on April 11 2016 and since is n Case received status.
Could you please throw light on did your case go through. What is the current status? Earnestly request you to reply please. Thank you very much.
