Our solar system was installed in January. With it, we had an immersion controller to divert excess power to the water heater. As time went on and we moved into the unseasonably warm spell in February it became apparent that the water heater system was not functioning so I contacted EEC and reported the problem.. It is now nearly May and nothing has been done! Despite numerous phone calls and emails no-one is responding other than telling me that they are aware of the problem and that someone will get back to me and arrange a visit. How long do I have to wait? I have not really made a fuss and have relied upon the company's professionalism to remedy this situation, but it now seems that I am being taken for a mug and they have no interest in customer support. I must say I am very disappointed. They were very quick to ask for my payment which they received within minutes of the installation being completed, but the are not quite so quick when it comes to sorting out customer's problems. I am very reluctant to post poor reviews as I was always told "if you can't say anything nice, don't say anything at all!" In this instance I have no choice. I am hoping that EEC redeem themselves soon and sort my problem out, but I'm not holding my breath!
