Last summer, I got approached by Luminus while at Media Markt. They convinced me that they are a better supplier than Lampiris and assured me that they would be cheaper. So I changed as of September. And indeed, my bill for electricity and gaz became 20 Euros less per months. But this month, they deducted me a large amount of money, and I realized that they had recalculated my use of gaz end electricity, and it turned out that it's been actually 9 Euros more per month than it had been with Lampiris. I wonder how this could have happened. From September till December, I lived with a flat mate, but I don't think that the expenditure was so much higher with her. I feel deceived now. Has anybody had a similar experience with Luminus?
