Bad repair service

On the 27/02/2019 Teljoy send a technician to service my aircon. The technician arrived at my home and started to strip the indoor unit to clean it. When he put the two swing blades back he told me that it is broken at the end and he must order two new ones. He even wrote it on the jobcard with the model number of the aircon. On the 04/03/2019 I started to phone Teljoy to find out when they are going to repair the aircon and every time they tell they will phone me back. On the 07/03/2019 still nothing happed and I logged a call again. Got a sms to say the call is logged. On the 13/03/2019 I phoned again and the answer that I got from Teljoy was that the company they use to service and repair the aircons told them that I broke the aircon. I have video footage of the day that they serviced my aircon and you can even see how the technician is trying with a lighter to melt the part together again. I am not happy since I am a client of Teljoy from 2006 They made a lot of money out of me and this is the service I get
