Samsung poor service

I have a Samsung Ecobubble washing machine which was purchased in September 2020 and as such is still under warranty. It developed an internal water leak onto the drip tray and I logged a call with the service centre. That process went smoothly and a technician was out to me 4 days later. He claimed he had repaired the leak initially but it wasnt the case and on the subsequent visit he cleaned the machine top to bottom and internally, claiming again that it has been resolved but like the first time it wasnt. I had him on WhatsApp and sent him videos and pics and told him its frustrating as the water continues to leak onto my floors and wooden door and frame and is damaging it. Initially, he said he will have feedback for me as I want a replacement machine if the fault cannot be properly diagnosed, but subsequently my messages fall on deaf ears as he doesnt respond, knowing the urgency. The frustrating part is that I have received 2 subsequent “recorded” calls from the customer service centre, having the audacity of being asked to rate their technician and their service, when the issue, being 3 weeks old now, has still not been resolved or followed up on by them, even though I raised it on both their calls and asked for escalation! Its the last time I will buy or advise anyone to buy Samsung products, as I suffered the same with them for my tv - their aftet sales service is non-existent.
