Beware Exec Air!

We paid for an expensive service on our two six month old units, they had been barely used, and the service was over R1 000. When it came time to put on the one we only use in winter, it would not warm up. My client and I could not figure out the settings. I sent the business an email, asking about the problem, and also why the inverter did not kick in. They answered my mail by saying they would send a technician out. As they did not mention a call out fee, I thought this would just be follow up to their service. They made an appointment, I made arrangements to be in that day, but they did not pitch. I contacted them again, and they said they would make another appointment. I asked them to let me know so I was sure I would be home. However, the technician just arrived, as I was going out. He was in and out in about 2 minutes, apparently they had changed the settings on our remote during the service. They did not even look at the inverter, nor say anything about it. I then received a R500 call out fee! None of this was explained to me, if they had just answered my mail, the whole call out would not have been necessary. There was some snotty remark about reading the manuals, besides my eyesight which prevents this, the very least they could do was say they had changed the settings, or put it back to how they were or at least say! We are going to be putting in some more aircons with a more customer orientated firm. They would not waive or reduce the call out fee, hence this review.
