Help please

We bought a washing machine at Game store And within 6 months the washing machine from Samsung stopped working We contacted game store and game store referred us to Samsung group as its their factory fault and the machine has a 10 years warranty. Now the machine can switch on and select the desired format to wash the clothes But all it does is ,it takes in water and the tub isn't moving but there is a sound that reflects that its done washing ,rising and spinning. But there is no movement Samsung people called us and asked us to diagnose the machine yet we know nothing about washing machines. And I eventually got angry and shouted over the phone cause now I have to take time off my duties/work to do their work while this machine has 10 years warranty and it broke within 6 months They sent two guys to come fix the washing machine And those guys eventually assessed the machine instead of fixing the machine They claimed that 1 ****roach 🪳 that they found in the machine is the one that ruined the motherboard of the machine hence why its not working But I can switch on the machine and select any cycle I want to wash without any hustle but they claim that the motherboard is dead They escaping the process of fixing the machine cause clearly its a factory fault and they have nothing to hide with. Now we are stuck with tons and tons of laundry for weeks Some was taken to a laundry and we payed R400 yet we have a washing machine at home Samsung people don't care or even have a solution for this. Meaning that we lost R8000 to a dead machine within 6 months yet it has 10 years warranty Ain't they selling us lies ? Every complainant was told about ****roaches also, no one has ever received any services within that stupid warranty they claim to provide to their customers. When I request for my money back they hang up on me and even my mum

Help please with a solution
