Horrible company that does not care. "Technicians" on support chat lie and constantly say that "modernization" is in progress and that it will be resolved in a couple of days. When I reach again after the date they gave, they say the same thing again, just with another date. This goes on forever.
It worked at first (2 years ago) and progressively got worse as time went by. Now I can't even work with 0.5-3 MBit/s in BERLIN? I wonder how this service works in the middle of nowhere!
