I have had the worst experience ever

I have had the worst experience ever . Bought a dishwasher which from day 1 was not drying . I was allocated 3 technicians in the 2 yrs of warranty. The last being Alwyn the most senior technician . They all saw the problem . Videos were taken and said to me I will get feedback . Each time feedback was “ No fault found “ 😡Everytime they came and ran cycles I had to take off work. Now I have an extended warranty with Hirsch’s and they are trying to resolve the matter . I had to take off work again to run a cycle as the fourth technician waited for an hour , Exactly the same was found . One technician admitted the machine needed replacing. Stainless steel *****s rusted 🫢🫤 I feel Whirlpool after sales is pathetic and their products are inferior therefore you don’t get good after sales service . I had taken this to the consumer council but they said they got feedback of “ no fault found” .
