Congés Intempéries BTP

Does it still exist? The voice server announces you 3 min of waiting and after 11 min we announce to you that it is overloaded and that it is necessary to call back. Already 4 unsuccessful attempts to get them on the phone, starting at 2:30 p.m., the opening time announced when I tried to reach them at a time when they are closed. Ah and there is a good chance that it will close before I am answered since at 4:30 p.m. the proof is over and that I had the time to write this message while waiting for a response and that bah not always. Very bad experience. I hesitate to do the 100km that separates me from them to finally have answers
