Arçelik DMX 9100 Washing Machine Bad Performance Complaint

I purchased the DMX 9100 9kg washing machine. After using it once, I realized it did not clean or foam correctly. Despite calling Arçelik five times within 15 days, I received the runaround. I declined the offer to repair it because repairing a brand-new thing seemed pointless to me. If the product will not be supported, I don't think it should be marketed. I mentioned my unhappiness and want to upgrade to a higher model, but was informed, "You bought it online, we can't help." However, I know Hepsiburada, where I bought it, is a respectable vendor. I'm not sure why I was dragged along for 15 days. Why use delay tactics when I have rights such as cancellation and return? If Arçelik is a worldwide brand, it must act appropriately. There's no repairing this washing machine; laundry is stacking up. Replace it or give a functioning version. I used your prior computer for 18 years and was extremely delighted, however the performance of this current one is inadequate. I bought an Arçelik product somewhere, and I want this problem rectified. I am not asking for anything else. It's awful to say "there's nothing we can do" over the phone.
