W.E.Geyers very very poor client service

W.E.Geysers seem to try wangle their way out of replacing a geyser that they installed under a 10 year replacement warranty. It has been 8 days since my Geyser burst and they still have not replaced the geyser. Their client service is so poor that they do not even contact me to advise the progress of my claim. Between Standard Bank and W.E.Geysers this is very disappointing and quite frankly ridiculous.
