Avoid this company!!! Every time they sent me bill there are some problems. They try to overcharge me by calculating different unit cost that is in my contract or they charged me for replacement of meter they never replaced etc ect. Every single bill there is a problem. This time when they try to charge me for replacement of meter that they never replaced I challenged them and asked why they lie to me and try rob me they said oh this is mistake and in "Goodwill Gesture" (yes they used this exact words Goodwill Gesture) they will remove that 200euro from my bill. They try to charged me 200euro for something that never happened and when challenged they call it Goodwill Gesture. Please stay away from this company.
