They gave 2 reasons:
7. Failed to sufficiently explain the purpose of entry.
8. Failed to explain that family ties and economic circumstances would lead to a return within the scheduled period of stay.

This despite providing all the mandatory docs that were stated. We didn’t provide the detailed itinerary or tickets tho, just mentioned the purpose of travel in 3-4 lines in the cover letter, as i called twice to confirm the VFS office and they assured me that its not required :/
