Dyson disappointment

I am a hairdresser, and bought a Dyson hairdryer dec 2021. In June 2022, it started overheating. I thwn had to switch it off, let it cool off, before I can use it again. I contact them, explained what the problem is. They said I must send it in, to the jhb office. I was without the hairdryer for 4 weeks. The problem was apparently that the filter was not cleaned. Even though I clean it every day after work. They refused to replace the product. Then in January 2023, same problem occurred. I had to courier it again, went without it for 2-3 weeks. Again the story of the filter. And no, they won’t replace it because it looks old and dirty..,, an use it everyday! And then in September 2023, for the third time in less than 2 years, exactly the same problem again. Overheats, lights flash. Switch off to cool down before it can be used again. So… is that what one would expect from a R6000 hairdryer?? I will not recommend a Dyson hairdryer to anyone I speak to! Very disappointed in the product and aftersale service.
