Hisense South Africa, VERY BAD SERVICE

On 30 September 2019, I contacted Hisense South Africa via email about my television that is broken, they rep**** quickly and on 3 October told me that a technician will be coming around. AND THIS IS WHERE EVERYTHING WENT DOWNWARDS. The technician came to check my tv set and told me that my tv is too old (it is not even 4yrs old!!!!) they don't have parts for it and he left without fixing it and he couldn't take it with as it did not fit in his vehicle. Eventually on 16 October 2019 another technician came out and took the television set to be repaired. It is now 29 October 2019, Nastassja from the helpdesk are not replying to my emails anymore and I am still without a television set.
