Power Africa apparently closed down without fulfilling services

Bought a 3 kw wind turbine from them end of October. Garentees and after services was promised. According to their website they existed 15 years. The unit did not supply any power. After many complaints, they send us a letter that they are going to replace the controller box, but the shipping will take 3-4 weeks. That was supposed to be here before closing for the Christmas season, so we were waiting for the new year to begin. The letter also promised that they will arrange with the developer in America for a visit to see why the turbine keeps on changing direction, as soon as it picks up enough speed to charge. We were sending reply emails to them from last week, but it gets back undelivered. So we tried to phone them, no answer. The rep, Meyer that visited us said he is not working for them any more. Another contact we had André, claims he's not working for them the past 4 years. so I opened Hello Peter and see lots of complaints now, that they closed down. I will contact the Consumer protection Act.
