Customer satisfaction rating

We had a problem with our RODI system and originally thought it was Puretec’s fault. Their management took accountably and focused on solving the issue. We later found out it was our fault for the system failure and I really respect Puretec for not playing the blame game and just focusing on solving the problem quickly.
