Late to appointment and poor service

We had an appointment on Thursday, 3 December at 12:00 to look at a garage door which does not work. The tenants took off at work to be there. 12:15 I was informed no one came. I called the office and I was told someone was on the way. 12:45 I phoned again, I was told they just sent someone. At 15:00 I received a call from the technician, saying that I must open the gate as he was at the property.<br> I sent him back to the office, as he was late and there was no one at the property any more. I emailed Annatjie to raise my concern of what happened, and to reschedule the call-out with no response. I got a call a week later to find out if I was happy with the service. I explained the situation and I was told that someone will be sent through on the weekend(12/12). When it was time for someone to come, I was informed after I had to call them, that there were no technicians available. We postponed to the Monday (14/12) night. I once again had to phone to confirm the time, I was again told that no one was available. I gave them another chance on Tuesday (15/12) and I was never contacted. I phoned and I was asked to phone the technician myself to arrange the call-out, which is not my job.
