Faulty Hair Straightener

I purchased a GHD Hair Straightener in January 2023. By April 2023, it was no longer heating up. I logged a return through the Hair Salon that it was purchased from and received a new straightener at the end of July 2023.(over 2 months later) l. Last week Friday (26th January) I experienced the exact same fault with my straightener. I immediately logged a warranty call (first thing in the morning) and received an automated response asking me for the serial number, which I had already provided. Yesterday I had still not received a response until I called customer service to complain. I was then asked for the serial number, which I provided for the third time and again, did not receive a response. This morning after REPEATEDLY asking for an update, I was told that a courier service would collect the faulty GHD IN 72 hours (which could be any day between today and Friday) and that I would then have to wait 7-10 working days to find out how they plan on resolving the ONGOING fault with that model of Hair Straightener. By the time I (hopefully) get a new GHD, the process would have taken 3 weeks (IF all runs smoothly). The service, response time, and product is so disappointing. When I asked the Customer Service representative how they plan on resolving this ongoing fault with that model, she was unable to answer me. So I will be returning my GHD every 7 months until the warranty is expired, and then I will be forced to either repair a product that clearly has a manufacturing fault, or purchase a new one and hope that I don't have the same problem. Up your game GHD!
