KSY Home Remodeling LLC review: Poor service repair

KSY was hired to insulate and drywall basement which was previously started and incomplete. Materials were left from previous serviceman. KSY did not install support for the sheetrock and aimlessly and carelessly affixed the sheetrock without supporting 2x4's which were in the basement. Drywall was cut unevenly and hap hazzardly nailed to the wall. They did not connect the utility sink and washer. When calling KSY to voice dissatisfaction Karief stated he would come "back out there". He has failed to come back and declined to issue a refund.
