Extreme poor and unprofessional after-sale service

Had Ruan Kotze install solar panels on the roof on my house. He had no problem dealing with the fact that it's not in his own town and promptly made the drive (60kms) to come and do the installation. The problem came in when one of the batteries failed. We had phoned several times and after finally getting hold of Ruan, made an appointment for him to come and fix the problem. Date set, it came and went without Ruan showing up to solve the problem.

This person has a real problem to honouring his promises, and his after-sale service is nonexistent.

I cannot get myself to convince others, to get his company to install solar panels on my recommendation.
