Beko Washing Machine Leaves Rust-Like Stains

I've been having persistent issues with my Beko washing machine since I purchased it, and the company has failed to resolve the problem despite multiple attempts. They've replaced both the drum and the door, but the machine continues to leave small, rust-like stains on white clothes that are impossible to remove.

I've reported this issue to the service center before, and they came to inspect it, claiming there was no problem. When I requested a replacement, my appeal was denied. I wouldn't be going through all this trouble if there wasn't a real issue.

I'm at my wit's end now, especially after my newly purchased dress got stained. It's become unbearable. I've attached photos for reference. Beko needs to address this problem immediately - all my white clothes are stained, and it's embarrassing to wear them. This is truly unacceptable, and I'm suffering financial losses as a result.
