Brand new Samsung washing machine booked in at Electracorp Bloemfontein

My brand new Samsung washing machine was booked with Electracorp on 24 May 2025. After a week they sent out a technician which told me that it was the motherboard. A week later another technician pitched with a new board but the washing machine did not work. Another week later he replaced the digital front panel but it was still not working. Another week later they picked up my machine and took it to their workshop in Bloemfontein where it's been sitting for 2 weeks now. They don't call back when they promise to do so and I've been calling almost every day since the machine was taken to the workshop. These people are the most useless I've ever seen. Even their Bethlehem branch tried to help but without any luck. Bloemfontein cancel the call as soon as Bethlehem put me through.
