They are horrible.
Badly reachable in case of issues and they don’t seem eager to help but only tell they understand and can’t do anything.
My internet connection is not working since last week. They agreed with me to send someone on day X between 12:30-16:00. One day before they changed the time to 11:00-14:00. When I called them to tell I can’t be there before 12:30 they threatened me with a €65 penalty instead of trying to help and postpone. They do whatever they want and suits themselves.
Go for Budget Internet in case you are craving headache.
