hi tone.. just been to vfs a couple of weeks ago and got my visa 7 working days after.
To be honest the atmosphere there is not good. I don't like it.
If I have only known, I could have just showed up there without booking it online because they don't really look for the appointment letter.
You don't pay the visa fee... just the service fee of 24 quid.
I did try to contact the Belgium Embassy first but I was referred to vfs
