SolarX non-exictent after sales service.

I have been helping some pensioners in this town. They asked me if I could look at their SolarX solar system. They tried and were told that they need a CoC and then never heard from SolarX again. I told them that I know nothing about solar systems but I would contact SolarX myself. SolarX has no interest in assisting us, they have no after sales technicians. I would stay clear of this company. These pensioners are 82 and 94 years old respectfuly.
