POOR POOR After care and poor quality product

Defy after sale service is really pathetic, I have had the same problem with my Tumble Dryer for months now and they just cannot repair it, I have waited now for more than a month for someone to repair my tumble dryer, you pay a fortune for a product thats supposed to last years and years to come this is the first time I am having so many issues with a Defy Product and its only 2 years old. My first problem job card *** was booked a week later it was repaired a week later I had the same problem, I called Defy, and was given job ***, a week later the same technician came and replaced the same part as the previous time. A month later and my tumble dryer did not work again, by then it was lockdown, I eventually managed to get a jobnumber *** and my Tumble Dryer was repaired for the 3rd time with the exact same fualt and the exat same part was replaced, this time by another technician, a week later my tumble dryer started to sound like a broken truck and made the loudest noises, I got a job number *** , they repaired it a week later and said the bearing fell out, I asked how do that happen and they could not tell me. A day after that technician was there my tumble dryer stopped warming again for the 4th time job number ***, this job card was booked more than a month ago, I do not recieve any feedback and just get told the technician is waiting for parts, 1st of all why must I keep calling to get feedback, 2ndly why do defy repair a product which has the exact same problem 4 times in a row in less than 5 months, surely they should have figured out by now, that what they are doing dont work, the parts doesn't work something else is wrong, I did not pay 4000 for an Item with a 3 year guarantee to have so much issues with it. Defy must replace my tumble dryer or repair it properly today still, poor poor service, abd to think almost all my appliances is Defy.
