suntank geysers poor aftersales service

I need to put this out to all prospective buyers of suntank geysers even though the owners accuse me of being ,yup, a keyboard warrior. Dont buy their geysers you will be disappointed to say the least. 10 year warranty means nothing, sales pitch. Just look at all their reviews ,all negative. YOU HAVE BEEN WARNED. Read their reviews for the answers.
