Poor quality of work

I have been trying to get a hold of the eThekwini municipality with no success. They disconnect the call after holding on for 20 minutes. They repaired a burst water pipe and dumped a truck load of soil against my fence to backfill which has resulted in my fence now collapsing. Is this the shoddy work we pay such high rates for. They are sending me from department to department and no one wants to accept accountability.
