Man i would take it back in there and demand them to fix it and fix it right .you paid the money make them redo it ,throw a fit you u have to ,but dont do anything to get yourself in trouble (boycot, picket the store) something happen to me like that one time and they said that they couldnt help me well i sent a friend in on time milling around and asking questions ,i had him ask if something went wrong with the equipment would they fix it because hehad herd that they wouldnt , he then told them that he couldnt but anything there because he didnt trust them ,the thing is if they think they are going to lose biz then they will take care of it .
