No after sale service

<p>It is now almost two weeks that I have been having an issue with one of the geyser air valves that is faulty and must be replaced, installation was done almost a year ago and it was confirmed to the installer that this unit was covered for the year but now no word from them ever since, not sure if they are buying time so that we can move past the 11th or if this is generally how they work, this is SHOCKING! </p>
