Very poor and unprofessional service

A simple example of the disappointing service I received from adt in George. I have been a client of adt for more than 10 years. In September 2018 I requested a re-installation after alterations took place at my house. The technician (Eugene) came and did the re-installation and left all the old wires, the packets of the glue he used on the floor in my passage and left. I called the sales consultant (Rudi Goosen) who gave me the quotation about it and he rudely asked if he should help take out my black bags as well. After sending an email to their branch manager (Steven Green) with attachments of how the technician left my house and airing my dissatisfaction I still have not received any feedback, 5 days later and not even an apology.
