Okay, I'll tell you what.
Add Mr.Kobylka to your FB page and ask him openly for a customer review or to chime in on the veracity of his name being attached to your glowing reviews. If I see that I may revise my opinion but, I am not holding my breath.
Honestly, I wouldn't be surprised if people soon start suing you for using their name without permission to misrepresent your business. You do realise that when using a positive review it is proper to ask that person if you may reprint it and only an idiot does not keep that permission readily available just for cases like this, where you claim he must have forgotten buying bloods from you(I willif it turns out he has never owned bloods).
