Predatory home improvement company. Took advantage of my Mom. she took out a loan for $32K ; paid directly to the DD Air conditioning (contracted vendor) and Heating by the State of MD. My mom was charged considerably for the work, where roofing was incorrectly installed on a low slope roof, where the vendor neglected to vent the exhaust fan (they installed), where the vendor neglected to seal the existing vents (which are now leaking) and where the vendor provided her no documentation of a warranty. My mom reached out several times over since 2012. I had to find an email address and the actual mailing address since the license number and the phone number on her paperwork were incorrect.
