Retrofit solar geyser

<p>Tasol solar installed a retrofit solar geyser system last year and told me I could save 30%-50% on my energy consumption/cost.Paid the R12000-00 and my electricity usage has since doubled (and this in summer).Called them on numerous times (they keep changing electricians)to repair,fix and adjust different components-still no change and no savings seen.Now they charge me for a call-out and say I am blacklisted.I would not recommend Tasol Solar-they are a rip-off!!!Would never have used them if I had seen so many negative comments on this site!!!!Seems like a "fly by night" operation to me....It was a waste of money-could have saved the initial cost and paid the normal monthly elect bill.</p>
