bad service

we bought a twin tub washing on the 05/09/2020 and by December this machine stopped working we then got in contact with the shop we bought the machine and they said that the guarantee is with Hisene and not with them well we then contacted the service center and told them that this machine is not working and that they must sent someone out to come have a look well weeks later someone came out and told my wife that there is a part that is broken in the machine and that they can fix the problem service order number *** but i then said i don't want the problem fixed this machine is brand new and there parts breaking i don't want this i want a new machine so the guy left saying that i should contact HIsense and tell them about my needs up till today nothing has been done and believe me this will not end here i will be going to the media with this complaint and how high i can go
