I Have been without hot water since the weekend, contacted customer service numerous times as my boiler is under warranty. Each time I call they claim that my boiler is not registered to my address or registered at all even though my installer has sent this off when it was installed in 2013. I have been sent a screenshot of a confirmation notice that he has had to go through and 're register it but still they have nothing there side. Customer service has a lot to be desired
