Geyser damaged on installation by Franke

This New Geyser serial no ***, was installed in Nov 2013 by Franke's suppliers.<br> Since installation, I had boiling hot water, although we asked the guys to make sure the temperature of the geyser is set correctly. Now, 1yr and 6 months later, my thermostat packed up and I had to replace the TP Valve. I called the Franke call centre, spoke to Pieter who said that the geyser is no longer under guarantee as this was a warrantee replacement already and the first one was installed 2009.<br> I had to call a plumber out at my own expense and pay for this repair, only to find that he discovered that the thermostat was bent and damaged on installation and could never work right or switch off when it was supposed to!! No wonder I had over-boiled water and ridiculous electricity bills! when I called the Franke call centre again to express my unhappiness with the fact that the geyser was damaged on installation by Franke, the same Pieter simply told me with a stroppy attitude that they couldn't do anything. BAD Service if a new unit is damaged by your installers and then I have to pay for the damage when it packs up!
