We have been waiting for three years for our windows to be repaired, they are commercial grade and came with a guarantee yet they form ice in the winter and leak. Damaging our dry wall and leaving the solarium too cold to be in. I have repeatedly called, emailed and documented our situation. They have sent numerous people yet all people seem to be passing the responsibility on to someone else. The amount of disorganization, lack of communication and lack of competence to solve the problem is very disappointing.
