My smart tv not smart after all

I want to share with the entire SA the horrible and unprofessional service I have been getting from Hisense and Makro Alberton. In January 2019 I bought Hisense smart TV from Makro Alberton. Around March 2019 it started to give me problems with internet connections. It will sometimes not connect to the internet. I phoned Hisense customer care and was told to upgrade the software. I could not upgrade it by myself and a technician was sent to my house. He kindly helped me and the problem disappeared for a couple of weeks. All of a sudden it started not to connect again. It will only connect after factory resetting it. I also realised that the screen was loose. Custer care sent another technician to my house again. The rude technician upgraded the software again and never bothered to check the screen. On 27 May 2019 I called hisense and complained to Karabo. He said he will escalate my complaint to the supervisor but I never heard from them again. After 2 days the internet connection problem had started again. I called back to find out when are they gonna fix the screen. They said they will send someone. This time no one came. On 11 June 2019 I took the TV to Makro Alberton and explained the problem. They booked the TV for repairs. On 14 June 2019 I got a call from Makro Alberton to inform me that the technician connected the TV to the internet and it has no problem, he also says there is no problem with the screen. On 15 June 2019 I went to the shop and spoke to Zuki (Makro Manager) and Ofentso (Hisense rep). I showed them that the screen is loose and they both acknowledged that. Ofentse said she will ask the technician to come back, she promised to phone me back on the very same day to let me know when the technician is coming. She never called back. On 19 June 2019 I phoned Makro to find out what is the progress. I spoke to Lindo. She told me that the technician will come on 20 June and will phone me when he arrives. She never called. On 21 June Ofentse called and apologised for not phoning on 15 June. She said the technician will be coming on that day. She will phone me when he gets there. She never phoned back.
