Road collapsing due to brickwork - now a hole

The bricks around the drain have slipped further and are now falling into the drain leaving a hole in the public road where cars and children walk over - very dangerous. This was reported previously in March and unfortunately it was marked as "resolved" by the council without being repaired so has worsened. The brickwork needs cementing in and the drain stabilising (as has been done around the drain next to the park in the same road where there was the same problem in March.) There is no way to access houses without driving over this.
