Dyson Broken Battery and Poor Service Experience Issue

I bought a Dyson Cyclone V10 Absolute Cordless Vacuum Cleaner from your official online site on May 21, 2024. In June, the battery life of the device began to decline, coinciding with our vacation plans. After coming back from our vacation on July 20th, we reached out to your call center to ask for assistance with our service. We noted that the battery was not charging and that the red light was flashing while it was being charged. A new battery was shipped on July 23. While it initially succeeded, it ultimately proved to be of no advantage. On August 1st, we were instructed to return the battery and were promptly sent a replacement body. Unfortunately, the new body was incompatible with the defective battery. We sent all the necessary items to the service center individually. We got a notification stating that the service has been finished, with code 2000, which confirms that the battery has been replaced. We contacted the call center and requested their assistance in ensuring that the old battery was not returned as if it had undergone any repairs. We addressed the matter promptly. We were informed that a fresh battery and body would be dispatched. Unfortunately, what we received was a worn-out battery and a malfunctioning device. We reached out to the call center once more and were informed that the battery had been replaced, but unfortunately, the body would not be replaced. We mentioned that the information we received was different, and the battery had not been replaced since the serial number remained unchanged. They mentioned that it was outdated and recommended that we take it in for repairs. I won't even bring up the apathetic and patronizing demeanor of the individuals we interacted with; that's their own problem. Does your brand value hold no significance? Today, on August 21st, Dyson sent an email stating that they have once again replaced the battery and conducted all necessary checks. We asked for expedited shipping but were informed that it would be dispatched in 48 hours. We inquired about the possibility of receiving a solution, but unfortunately, the response we received was not customer-oriented and focused on finding a solution. I'm wondering if there has been a decline in your brand value and customer care. I initially chose your brand because of its reputation for quality and assurance, but it appears that those aspects have diminished. Consistently delivering faulty products without offering any repairs is incredibly frustrating for us. We can't help but wonder what the advantage is for you. Please address this matter promptly.
