The information submitted regarding the justification for the purpose and conditions of the intended stay was not reliable
What the officer was reading
The most misread ground on the form, and the one most Indian applicants get. Read it beside ground 2: ground 2 says you did not send it, this one says you sent it and it was not believed. Nothing was missing. The officer read the file and the story it told did not hold together, usually because the trip does not match the person taking it: business-class flights and five-star bookings against a modest balance, a fortnight in four countries with a day in each, an itinerary somebody else clearly wrote.
What changes it
Not more paper. The file has to describe a trip the person in it would actually take, at a cost they would actually spend, for a reason they can explain in their own words. That usually means changing the trip rather than the documents, and it is the work this firm actually does.
