France Télécom help line
Since we returned to Creuse, a month ago, we've had an ongoing series of troubles with our landline....I called 3900 several times, and after over 30 minutes per call, I was either disconnected or assured the problem was resolved (it wasn't). So today I tried the anglophone help line 0969363900--since my French was (slightly) better than the tech's English, we ended up speaking in French. He was able to resolve the problem; he then mentioned that the people who respond to calls to 3900 are fools, and are generally based elsewhere (e.g. India), but that the 0969363900 crew are generally in France, and are much more competent. This is consistent with what I just went through. The main disadvantage of the anglophone help line is limited hours (and, often, prolonged wait times). If you have a telephone problem, even if your French is excellent, don't waste your time with 3900.
