I am also in the same boat..
My wife has submitted her passport on June 18th..
Still I haven't received anything from them nor any status change.
I have done CSE in July, August without any success...
Now I have emailed Immigration minister and also planning to talk to my MP about the status...
I don't how these people can hold your passport for more than 2 months..
I Can understand your frustration, we can't predict CHC VOs they give us surprise at any time, only we have to be patient.
You have filed your application on 8th March and your 6 months waiting period will end on Sep 8th,I strongly advice kindly wait till Sep 9th than approach your local MP for intervention.
Even If you approach CHC Delhi before 6 months of processing time, the VOs is not obliged to answer anything before processing time & if they are answering specific enquiry then it's just a luck friend and more over there answers are very generic & never brief detailed.
There are so many people in this forum who are waiting for PPR since two months and waiting for visa more than >45days after submission of PPs. Some few lucky persons who have got their passports back within short time, so we cant compare with them every ones application is unique in its own way and they are many applicants whose passports were held by CHC for over 4-5 months!
Let us wait patiently and all one by one will be receiving visas soon !
