I got a Schengen visa from the Belgium embassy for the validity of 21 days but for 7 days stay.
I got my passport late from embassy and my approved leave was over already due to delay in application process. My travel dates were from August 6 to August 12, but I got my passport on August 17 with the validity till September 5.
I am unable to travel due to unavoidable circumstances.
Will it make any problem for my future applications if I don't use this visa?
By the way, this is my second Schengen visa. The first one I already used some year and half ago.
