******* System, Come and Remove It!!!

We moved in to our newly built home just before the end of April 2022. The Geyserwise system hasn't worked ever since it was installed just before we moved in. It only heats up when it's hot outside and when the weather changes and one uses the hot water it never heats up again. If we decide to bath in the evening the water will be cold in the morning and we have to use a Kettle for hot water. It doesn't switch to electricity when its cold! Or if the hot water has been used. We have scheduled time slots for the electricity to kick in but it never does. It is now DECEMBER and we stll haven't received assistance from Jimmy who keeps asking for a call out fee before he can come and fix whereas the initial installation was faulty from the get go! We need this fixed or removed as it has proved to be useless anyway!!!
