Shocking service, No comminication, Poorly managed

I arranged to have Isotherm installled in my ceiling on Saturday 5 March 2016. I requested that the installation start at 08h30 in my morning. It is also very difficult to find my house(even with a GPS). I gave Warren Lategan my basic travel instructions in an email message, plus my request to start at 08h30. None of this information was passed on to the Installation company who operate from Centurion PTA. I phoned Warren on his cell at 08h31 and he did not answer, I then called the 086 number and a man called Kevin answered. At this point I knew all my plans for the day were ruined because of the late start. The person who was to install the isotherm phoned me at 08h35 because Warren had SMSed him as a result of my missed call. Warren passed the buck. Did not take ownership of his mistake, Warren is 100% accountable and responsible for customer service. I paid a 55% deposit to have this done. The installerr only arrived at my home at 10h20am and in the process got hopelessly lost even though they had a GPS. The job finally finished at 12h40pm. So disgusted. All of this could have been avoided if Warren had managed the transaction and communicated the information early. Shocking!
