Visa issued for 33 Months
As you can see that after getting the letter on 3rd August 2016, I had no contact from the VISA team till 20th October 2016, which is nearly 2 and half months!!
You can follow my timeline however, since every case is different, you can never be sure about the exact timelines.
I received all correspondence through emails and after submitting my passport on 25th October 2016 and then paying the IHS fees through the link given to me by VISA team on 31st October 2016, it took me nearly 15 days to get the passport back.
I know the wait feels really long, however, you need to look at it this way that this is probably the only way forward so its better to be patient than impatient because theres pretty much nothing you can do at this stage from your side but to wait and be positive.
So relax and keep your hopes high!
Good luck

Keep smiling.
