Gave me a discount. Then 2 months later increased the prices, effectively removing any discount that I've got. "they said 10% off electricity and gas rates", but they don't guarantee that they will keep the rate the same = super clever. BE CAREFUL with them. Also, their customer service is super slow, had to email them 3 times to get a reply. Their 200 euro offer is pretty good, BUT given that I am now overpaying around 10 euro per month, it is effectively 80 euro benefit (200 - 120 euro), which is a lot less than other offers on the market.
