Game/ Mall @ Carnival bad customer service

I bought a defy twin tub 18 kg washing machine at Game mall @ carnival on February 2024. On the 27 June the machine stopped working I went instore to report the matter they said they will send technicians to come look at the machine. The first technician said the motor was broken and he will send another technician to come and fix it. The second technician came 5 July replaced the motor but still the machine wasn't working he then said he will return the following day to replace the switch (buttons) which he never did he even left my machine open. The following Monday I contacted defy and the manager of game they then sent another technician on the 18 July who took the machine with him and returned it the following day because he claimed that the second technician messed with the wires. 20 July I tried using the machine after 2 loads the machine stopped working again. I tried contacting defy and game customer service but no one is willing to help. One month later game doesn't want to give me a refund or an exchange and I still don't have a washing machine.
