Game disappoints

I am very disappointed in the service received from Game retail store and Defy. i purchased a washing machine cash on the 9th September 2023. The machine was delivered and had no inlet and outlet pipes. i sent an email to the store where the machine was purchased and not even an acknowledgement of my email. after buying my own pipes and trying to use the machine it was not working. the water just fills doe not stop and the drum does not spin. Email sent immediately to Game and Defy. the technician came out on the 22nd to inspect the machine and said the mother board is not working and the fuses are blown because of that. i receive calls from, Game head office and all they say is they are looking into it. the last call i received was that they cannot exchange my washing machine as i have opened it. Please help me understand how i would have know the mother board was broken if i did not try to use it. do they think we have Xray vision to see through boxes and covers
