AEG - very bad quality product

AEG product, and Service manager useless. Bought Brand new AEG 7kg front loader from Makro Silverlakes on 01 May 2018. Machine was delivered to my house on 02 May 2018 approx 15:00. Machine broke morning of 17 May 2018 and I immediately contacted Makro, explained to exact problem and they promised to get back to me. The machine has a Childlock function. After switching the machine on, selecting your cycle, press start, then hold in “Temp” and “Speed” buttons at the same time for approx 3sec to engage Childlock. We have done this since the machine arrived without problems. Morning of 17 May 2018, the childlock function will automatically engage as soon as I switched on the machine, which means no cycle can be selected nor can the Start button be pressed. Machine can ONLY be switched ON or OFF. Tried numerous times holding the mentioned buttons in to try and disengage childlock function to no avail. AEG manager - Mr. De Bruin contacted me 07:00 Friday morning 18 May 2018. Tried to explain to me over the phone how to disengage the childlock function by pressing the necessary buttons for 3x seconds. I told him I am aware of how the childlock functions works and the whole problem with the machine. He then understood there’s a problem and promised to send a technician. AEG technician arrived Saturday afternoon 19 May 2018 to come snd show me how to disengage the childlock function. After AGAIN explaining the problem and he himself could not get the childlock function disengaged, he spoke to Mr De Bruin who then asvised the PC Board needs to be replaced. Due to a lack of spares available, my machine MIGHT be fixed by Wednesday 23 May 2018. I do NOT WANT a brand new machine only 2x weeks old already broken and needing replacement parts etc. Who knows how long it will be till it breaks AGAIN. I request a refund or brand new machine
