But yes, that was my original question... but I figured it out; The unsatisfied customers are unsatisfied because they can't get the goods they need and yo provide more goods you need more shop, I got that after posting my original question BUT ....

I am having a lot of difficulty balancing demands and offers in commercial, Industries AND residential.
I am now at 60K population, my map is almost full and only to satified my medium wealth I would need to build shops a third of the map ...
I have unsold goods for high wealth shops and at the same time, shops closing complaining of the lack of merchandises.
