UNFAIR TREATMENT BY ALPHA METERING

I had a very bad experience with alpha metering where I bought a property and was registered 27 March but my electricity meter was blocked because of the outstanding amount. Even after I send the the registration letter stating the date they never cared as long as their money was paid. They did even try to resolve it with the previous owner. They were never told that the property was sold but after proving it to them what did they do NOTHING. Because they could see it was never my fault and they have a deposit from previous owner. But ke I had to pay to get electricity not that it was a choice.
