Tech dept bills but problems continue.

We have a long standing problem with our alarm system. In April technical came out and literally did not fix anything. Just trouble shoot and we were charged R495. Turns out it was a batteey fault and we fixed it ourself. Fast forward 6 months later, more tech problems, get shoved pillar to post by control room, when you call tech is apparently always in meetings. Messages left. In the mean time ee have a massice crime surge in the area and it seems like they just dont give a damn?!?
