You could just have written a bad FR and left it at that because then almost nobody in here would visit the place.
To draw attention to the place to the authorities is uncalled for no matter how badly you have been treated because it will pretty much make all other places apprehensive about doing special service if they know that people from SBF will expose them to raids.
It would be enough to tell them in the shop about SBF and that a bad review here will be hurting their business.
Maybe that approach should be tried first before drawing too much attention.
Just a suggestion
