Well this interesting you see. When goods are sold in the UK, the contract is only ever between the retailer and the purchaser, never the manufacturer. This is why a "manufacturers warranty" is only ever in addition to a consumers statutory rights.
However, if a manufacturers warranty is offered, providing any neccesary terms & conditons have been met, that warranty has to be honoured. But there are no specific clauses or requirements which the manufacturer has to adhere to regarding timeframes or service levels, and so on. And of course if you think about it, once a product has been sold, there is little incentive for the manufacturer to offer a gold-plated 7-day-per-week customer service like Dyson does. Dyson did that beacause -like so much Dyson does- Dyson wanted to do it. In that respect, they have done nothing wrong as it's a free country. But it didn't stop me pondering how cost-effective it was so far as business choices go, and how much money it awarded Dyson in terms of repeat custom (and indeed how it was measured).
Put simply, if a vacuum cleaner call-centre is open at 5pm on a Sunday, people who need to use it will ring in. If it is not open, they will have no choice but to wait until such time that it is open. A vacuum cleaner problem is so far from life and death that I doubt anyone actually expects to be able to deal with it at the weekend anyway. Dyson is proud of it's awards for customer service, and so it should be, but if that same customer service is costing them lots of money, that award becomes very expensive.
Don't get me wrong, for what a Dyson cleaner costs to buy, I think the least one can expect is some sort of longevity, whether that comes in the form of a durable product, or a more flimsey one which has the back-up of a warranty. I just wonder sometimes what all this after care costs Dyson.
