Maids Causeway toucan crossing cycle detectors not working

For several weeks now, ever since part of the surface of the path was repaired, the cycle detector loops at the crossing of Maids Causeway from Midusummer Common to Fair Street have not been working. This means that cyclists using the crossing have stop and press the button unless the road is already completely clear. Does anyone know any more about this problem, and to whom should a complaint be addressed?
