Beko Washing Machine Leaves Oil Stains

The Beko CMX10120 model washing machine I bought with confidence 2 months ago leaves oil stains on clothes. The service accepted that it left oil stains and made a one-to-one replacement. The machine that was brought leaves more oil stains than before. The service came again. A trial wash was done with the fabric they brought, although there was an oil stain, the service personnel claimed that "this stain was on the fabric they brought before washing" and said there was no problem. Since the problem persisted, I called the service again. The service tells me "we checked before, there is no problem, are we going to come and have tea at home, if there is a problem, go to the Consumer Arbitration Committee". I insisted on a different technician from the same service. The person who came said that the machine was already oily and opened a request for replacement or refund. They said the drum would be cleaned. The drum was cleaned 2 days later. When we washed again, we saw that the problem was not solved. There are no clothes left at home without oil stains. It's not just the cost of a machine that the clothes go to waste. I opened a request again. I called customer services and they gave me a WhatsApp number. They say send photos of the stained clothes to this number. Up until now, the service has come many times, they took pictures of the clothes many times, even the service accepts that the first machine that came and the second machine that came after the change were defective. However, they are still asking me for pictures in order to prolong the process. As a Beko user for 13 years, I have become completely estranged from the brand. Even companies that we can call under the counter and sell machines for half the price of Beko, which do not even have a proper institutional structure, do not victimize their customers this much. From here, I am calling out to all Beko managers, technical service and the people in the unit that examines and decides on these incidents. We are all consumers. Have you ever empathized? Have you ever put yourself in the shoes of us, our customers? In short, is your conscience clear? How long will this process continue like this?
