Dyson V12: 4 Months for Wrong Part, Broken Head & No Suppor

For our Dyson V12 vacuum cleaner, we reached out to Dyson customer services in December 2023 regarding the breakdown of the carpet nozzle and under-furniture adapter. They inspected it via video call and assured us that new parts for the two broken components would be sent to us. However, due to stock issues, they notified us that the products would be shipped after New Year's Eve, so we began our wait. Approximately 4 months later, in March 2023, they shipped the carpet headboard to us. However, since we were abroad, we could only check it 3-4 weeks after the delivery arrived, and we discovered they sent the wrong product. Moreover, because they didn't deliver the carpet head for about 4 months, we had to use the hard floor head on all floors, causing it to break.

Throughout the ongoing process, despite explaining the issue to Dyson customer services numerous times and detailing it to every representative we spoke with, they only seemed concerned about retrieving the wrong head they sent. This morning, the representative who contacted us was solely focused on the return of the incorrectly sent head and requested us to explain the issue again when we brought up other concerns. Frankly, we're exhausted from repeatedly explaining the problem to them.

Regarding the problem with the hard floor head, they stated that they "could not provide support for the malfunction caused by the product being used on the wrong floor."

To summarize:

Dyson has failed to supply the under-furniture adapter and carpet nozzle for about 4 months.
Dyson shows little concern for anything other than retrieving the "wrong" carpet head sent 3 months after our request.
Due to Dyson's inability to supply the products, they refused to support the hard floor nozzle, which broke down due to incorrect usage.

They question us on every call as to why we didn't open the delivery immediately and inform them as if it's our fault. The return of the carpet head is their only focus; they've overlooked our other complaints. For months, they've blatantly stated they won't support the hard floor nozzle due to "User Error." We've explained the issue repeatedly to every customer representative who calls. I request urgent assistance.
