Pathetic after sales service

We notified Jon Taylor about 3 weeks ago because the wifi connected to the security cameras were not working. He makes appointments and never pitches. He does not even have the decency to call and tell you his not coming. We have to sit at home whole day and wait. The next day we phone again and the same thing happens. On 2 occasions he rocked up and nothing was fixed. He is a complete waste of time..... Im am almost sure he does not know what his doing. Today he sends technicians with absolutely NO instructions. Jons boss, Martin Botha was also supposed to call me back today after a meeting with Jon. Im still waiting... I managed to get hold of Jon and as he wanted to speak to the technician, i told him to use his phone to call the technician as I have wasted far too much money on calls to him. The technician is still waiting. WELL i thought Jon was the problem, but i now see its his boss Martin Botha as well. PATHETIC SERVICE. We need to find another security company
