Dyson Failed to Replace My Faulty V15 Vacuum Tube After 8 Months of Waiting

I purchased a Dyson V15 vacuum cleaner, but the upper part of the vacuum's tube does not fit properly and wobbles. I contacted Dyson customer service on June 3 and reported my complaint. They called me via video and confirmed the problem with the product. They assured me that they had recorded the issue and would send me a new tube. However, months have passed since then. I have been messaging their WhatsApp support line since June 3, asking, “Where is my tube? When will you send it?” Their responses have been excuses like: “There’s a production issue right now, there’s a delay due to high demand, we’ve sorted it out and will send it soon, your request has been forwarded to the relevant team, don’t worry, your issue will be resolved shortly.” But nothing has been resolved. Today is December 24, and I have been waiting for the tube for nearly 8 months. This is utterly irresponsible behavior from a company that does not stand behind its products. They seem to be waiting for the warranty period to expire without doing anything. The vacuum is practically useless. It works erratically, sometimes not at all. I charge it for hours, only for it to show a “No Battery” warning when I try to use it. The purple plastic seals designed to prevent air leakage are broken and keep falling off. The vacuum heads don’t fit properly, and the product's internal mechanisms behave erratically. Pressing the trigger only starts the vacuum after 4-5 seconds. This product is only two years old—how much could a vacuum deteriorate in two years? We’re not abusing it; we simply use it for cleaning and store it properly. Yet it seems like a 15-year-old product due to how poorly it performs. The vacuum has essentially deteriorated on its own while sitting idle. We didn’t buy such an expensive product to use it for just one year. I demand that my vacuum cleaner be replaced entirely with a new one. If this issue is not resolved, I will file a lawsuit for both material and emotional damages. I have all the evidence: messages, conversations, the errors shown by the product, its malfunctions, and all related records. If Dyson does not replace my product entirely as a result of this complaint, I will immediately take legal action. I do not want any alternative solutions—I only want a full replacement.
