You're not alone!!! :=) On the same boat since early July. One difference is I had two voice mails from them (one month ago) regarding minor applicant.
I called every number listed here

A lady answered when I called Ambassador Prabhu Dayal's (Consul General) number (212) 774-0601
She said there is a huge back log, especially because the photo machine and website was down for three weeks.
She also said people from every department are helping the OCI department to process the applications.
Hope they get to ours soon.
My question is if there is a back log how are people who applied few weeks ago are getting acknowledged while who applied few months ago are still waiting?
