Don't buy UniPin prepaid electricity!

<p>I purchased a months supply of electricity from UniPin. When I got home I disovered that my prepaid meter screen was malfunctioning and CityPower came out to fix it. But after it was fixed some of the settings were changed and the UniPin vouchers no longer worked on that meter. Therefore I lost all the money I spent on the vouchers.</p> <p>I have emailed and called UniPin numerous times but nobody at UniPin ever responds. If you want to buy UniPin then you should know that if anything goes wrong they will not assist or refund you.</p>
