FOR YOUR OWN GOOD KEEP FAR AWAY FROM THESE CRUEL THIEVES!
Just beware if you are offered any kind of bonus/offer to join this energy company, as I'd like to warn you, as chances are, all the offer is, is bait to hook you and then you're stuck with them (if you can change company then do so asap).
Once you're with them, they play around with you as if you're just some tool for their own money making, similar to the way drug dealers may use people on the street. Once someone uses them, they blackmail you and then you're stuck.
They deal in scandalous, criminal and generally speaking illegal and underhanded activities, with the aim to force you, or put you under the impression that you're the one at fault irrelevant if it is true at all!
They will even randomly add huge sums onto you're bill, and then demand payment and threaten bailiffs etc. if not paid - yes - outright daylight thievery!
They really know how to provide the most polar opposite of any form of customer service.
They can contradict themselves, trip over their words in attempting to frame you, but without realizing, actually incriminate themselves in middle of attempting the above. They will answer the phone, but the minute they realize you are calling because of anything that will not serve them a benefit in some way, they hang up on you. They have no mercy, and will drink you dry.
DON'T DON'T DON'T fall for their traps, for your own good!
There are enough reputable companies out there to use, it is a shame for someone to fall for these cruel pitiful-answer-for-humans.
