Unhappy with geyser replacement

A new geyser was installed outside my house because the Brakpan insurance guys could not open the roof. it would have taken longer as they had to get contractors to open the roof. I now wait five times longer for warm water. Nedbank send another insurance company in June to come and have a look and I showed them how many water gets waisted before we get warm water through the taps. When nedbank was contacted 27 July it was advised that the call was closed in June, without fixing any errors, so they had to reopen the case again. No one contacted me and again I phoned 5 August, Moses promised that someone will contact me the same day or the next day but still no one contacted. <br> <br> Nedbank never advised me about a gas heater which I only recently learned about that can save me a lot of electricity. <br> <br> I have been put in a worst light and I want my geyser back in my roof where it was originally. I waist a lot of water as well as electricity.<br> <br> I have to phone after nedbank all the time waisting my airtime too and when it suits them they just don't bother about me and my concerns and close calls when they feel like it.<br> <br> A urgent response to this matter will be appreciated!<br> <br>
