Disasterous Duratherm Geysers

Purchased a Duratherm Geyser from Plumblink 3 months ago. The element has burnt out and the geyser has burst. Plumblink are not interested in replacing the geyser and Duratherm are not even contactable. In the meanti8me we are without hot water and everyone is either missing or not interested in assisting. You are dealing with Plumblink or Duratherm at your peril. Both are a disaster. STAY AWAY
