The employees of this firm are extremely rude and unprofessional and will resort to underhanded and dishonest tactics as soon as they make contact with their target. Under false pretenses, they will make baseless threats of legal penalties in an attempt to secure a quick payment for totally unsubstantiated amounts. I would recommend that anyone dealing with them ignore their threats and demands until they have looked into these threats for themselves (to see if they are even legitimate, they probably will not be) and verified the amounts demanded. They will initially refuse, but people should demand as much documentation as possible for the amounts requested. Only when they have verified their likely false or exaggerated threats should a person look to cooperate with Wilber employees, ideally with an attorney if possible.
