Applied for DS provisional back in April online.
Ticked medical condition and got some forms. Completed them and returned them 6 weeks ago.
Just received some more forms 10 days after being posted I have to return 14 days from date if letter 
I don't understand what they want and the phone lines just always say they are receiving high demand, use website and "goodbye".
The forms we completed are because he has a physical condition and we did put he is also on the autistic spectrum.
These new forms are the same on the front but the back asks about the condition he's been diagnosed with and ask his MH nurse or CPN if needed for advice. 
It appears to be about a MH condition which he doesn't have and didn't disclose and about his recent drug and alcohol use! (He's never had either!)
The letter or form do not actually explain what condition these forms are for and I can't actually speak to anyone to find out why he has them.
But they won't continue the process and may cancel if revoke the forms if they are back late (which they are now overdue).
Anyone able to help?
