Poor service and quality control

Extremely poor quality control, low pressure solar geyser burst, was replaced and the new one burst the very next day. Was replaced by Kwikhot but said I no longer had a warranty as geyser had already been replaced. 2nd geyser burst and same story - geyser was installed but was faulty and leaking the very same day. Call was logged for another burst geyser and technicians were sent out but didnt bring a replacement geyser so had to wait another day, in all a week without a geyser isnt acceptable, really poor service.
