DAVID WILLER OF ILLINOIS (LISLE AND OAK BROOK AND ELSEWHERE) IS A FRAUD. HE RIPS OFF CONSUMERS WITH FALSE MARKETING TO MISREPRESENT HIMSELF AS SOMETHING HE IS NOT. HE LISTS GENERIC REVIEWS TO CONVINCE PROSPECTIVE CONSUMERS OF HIS INTEGRITY BUT THEN DOES NOT DELIVER. SEE CERTIFIED WARRANTIES CORP OF OAK BROOK ILLINOIS WHERE HE SOLD HOME WARRANTY BUT THEN SHUT DOWN AND DISAPPEARED WITH NUMEROUS OUTSTANDING CLAIMS IN MULTIPLE STATES INCLUDING ILLINOIS AND LAS VEGAS. RESEARCH HIM IN THE STATE OF FLORIDA ALSO FOR A MORTGAGE FRAUD SCHEME IN WHICH HE WAS THE PRIME CULPRIT. JUST GOOGLE DAVID WILLER SUN SENTINEL FOR FULL STORY. DO NOT DO BUSINESS WITH THIS GUY. HE IS A TOTAL CON ARTIST AND WILL LIE FOR PERSONAL GAIN WITH NO REMORSE AND WALK AWAY.
