NuBath job poorly done

Bathroom refurbishing project sloppily done. Didn’t start job as initially scheduled. Left black tar spots on floor, smudge hand prints on walls, corner caulking amateurish. Brought two different trainees to perform work. Once NuBath was paid they ignore followup customer questions. Although work was done by NuBath company, NuSash and Weather-Seal seem to be under same ownership. I would welcome hearing from anyone who took a chance with NuSash or Weather-Seal.
