Does not come back on their word

Subscribed to On Air for Explora 2. They instructed Mulisim to do the Job. They did not do the job properly and had to phone constantly to come back. When they came back they damaged the electrica wires. I had to get an electrican to fix the wires which cost me R1500.00 I spoke to the manager Mike and he was going to send an electrician to inspect. To this day he has send an electrician, I contacted On Air as they contracted out their work to Mutisim and nothing was done about it.
