Don't buy a Duratherm geyser

Our Duratherm Geyser burst a week ago. We were referred to Duratherm warranties which we have been trying to call for the last 7 days. Most of the time the hotline number is not being answered but sometimes, when lucky we get through and after long waiting times in the queue we are being told we will be called back which NEVER happens. 7 long days, without water and requests to be put through to a manager are answered with "they are not answering their phones!". Finally they promised to send a plumber to assess the situation but he didn't rock up and the show started from the beginning (trying to get hold of them). They shove us around like we have never in our lives experienced. So interesting that they are still around. If you are contemplating buying a new geyser : don't buy a Duratherm!
