Worst Service from Hisense..utterly disappointed and disgusted

I have a hisense washing machine which started giving me problems in August 2020.i reported it to hisense as it was still under warranty. Hisense appointed technicians to assist and they found that the pc board was broken and was going to replace it but i was advised to continue using it. Since September 2020 I have been struggling with Hisense. I have received three different job numbers and every single time I get SMS saying the job has been cancelled..after numerous phone calls and emails to the customer service call centre aswell as Head office in Cape Town I have still not received any response or feedback. I have spent so much money on airtime to phone every second day.most of the time the lines are unavailable and when I do get hold of someone they first want to check with the technician and promises to get back to me but never does. 4months later I am at wits end. Disgusted with this terrible service and sitting with a washing machine that's not spinning my washing properly, switches off at any time during a cycle and also having a smell of burn. Which is not only a safety risk for my family but also costs extra electricity for having to spin each load two or three times.
