Bought a cordless dyson V10 a year ago and the roller head stopped working in May 2024. Had the warranty on the product so contacted Dyson to ask for a replacement. Four months later and after countless phone calls we still haven't been issued the replacement. Their customer service is the worst I've experienced in years and that really saying something. The customer service operators don't speak good English so they don't understand you and you can't really understand them. We've been told on four occasions that a replacement part would be sent by DPD and it never has.
