Faulty part from Defy

On the 22nd of March 2024 I went to Defy at Arcadia to buy the mother board for my 15kg washing machine that I bought at defy. I was told that they're going to order it and it will take 7 to10 working days. On the 2nd of April I called them and they told me that the part has arrived. I went there on my lunch time to fetch it, they gave it to me without invoice. I called the technician to come and install it and when he finished he tested the machine and it was working. On Friday i decided to do my laundry and the machine was not switching on and off but the blue lights were on. I called the same technician that was installing the part, he checked the machine and he told me that the part is faulty because it can't stop working within 3 days.

I then called Defy to tell them what happened, the lady that answered told me that if that part was installed by my technician they can't help me because they have their own technician and I ask her why didnt you tell me that before I took the part with me and she told me that shes gonna ask the manager to call me. I waited for their call until I went there on Tuesday on the 16th with that part, and the manager told me the same thing that I was told by the lady and he said its written all over their walls. When I was there I've never even look in their walls I didn't even see that and he also told me that its written in the invoice. I then told him that they didn't give me the invoice and he asked who was giving me the part I told him that it was a white guy . He said there is no way that they can give the part without an invoice, I asked him to look in to their cameras and see if they gave me the invoice, he didn't answer that he just said theres nothing they can do. I am very frustrated because I had to wait for full 3months to buy that part
