SAMSUNG Washing Machine: 15Kg Top Loader

My previous Samsung front loader lasted me around 8 years, which is what prompted me to purchase another Samsung Washing Machine (from Hirsch's Waterfall) - only this time I opted for a top loader, and my God, was it the biggest mistake I could ever make. The unit was purchased on 30 Nov 2022, and I only started making use of it in Jan of this year (2023) and I started to notice that my white clothes were being stained, I ended up logging a ticket with Samsung, for them to investigate, it took a while but eventually a team came out to investigate, they took pictures, and from then, absolutely nothing happened. It was transferred from one person managing the incident, to another, and not a SINGLE call was received back from Samsung. I was told, to go and use Vinegar and Bicarb to clean the drum, to which I asked - why am I cleaning the drum of a new machine, this doesn't make sense, and I was told there's nothing else that can be done. Can you believe that? In any case, I did was was recommended, and to date, now in July, I have the same machine, same problem, no assistance from Samsung, or the store I purchased it from (The salesman just stopped taking my calls now) and my clothes continue to be stained, together with bedding, etc. This is the last time I would purchase a samsung unit, the after sales service is just **********. In addition, I purchased an extended warranty, but for what really, when my issues cannot be fixed within the normal warranty period. I don't have the money to go purchase another unit, I'm stuck with what I have, and it's sad that Samsung refuse to assist me.
