Vehicle not repaired for two years

In November 2013 I took my Toyota Camry for a service. When I came to collect the vehicle the indicators where not working. The service consultant Audery Bezuide acknowledged this as their fault, as there was no problem with the vehicles indicators when I had brought the vehicle in. She called a technician who then said he would sort out the problem. Thereafter I called Fury Toyota several times to find out on the progress of my vehicle but no one had any feedback to give me. In February 2014 after several calls I was informed while the technicians were busy they mistakenly burned out the harness of my vehicle and they were in the process of ordering a new harness from abroad. At this point I was becoming aggravated so I set up a meeting with the owner and the manager who put me at ease. In September 2015, I had still not received any word on my car so I went to enquire at Fury Toyota only to find out that now it does not even switch on. The company is not getting back to me and it seems as though they are ignoring my attempts to find out what is happening with my car. I am very disappointed at their incompetence and lack of good service.
