GCarbon a ripoff

GCarbon guaranteed a 30% saving on electricity use age, I installed the unit in August 2014 and has been trying to get someone at GCarbon to proof to me a saving, after numerous calls Evert sent Peter to collect the monitor and 4 months prior and 4 months after installation electricity bills to calculate and proof a saving, nothing ever materialised, I have been sending mail after mail to discuss the issue but you cannot speak to anyone on management level just e-mail and nothing is happening.<br> The amount I paid was not small money for nothing, its hard earned money, that's the frustrating part, money spent for nothing in return.
