Solar Geysers by company who dont do solar

So I bought and installed (professionally) an XSTREAM GEYSER - Great geyser but been saving up for the SOLAR panel. So finally asked Xstream to courier me the solar panel which they do, with no fittings, after telling me I can literally fit it myself. Its taken me a month to find a solar company who has the right brackets to install this panel but the company does not do plumbing. Im now told it will cost me R8500 to do the plumbing as I have to install a circulation pump. After contacting Xstream again to find out why they sold me a panel that cannot circulate the water they have just said they don't do solar and cannot advise me any further . Company is Xstream SOLAR Hot Water www.Xstream.co.za But who dont do solar but will sell you a panel and then have nothing more to do with it???
