Dyson V12 Repairs Cancelled Due to Stock Shortage

I took my Dyson V12 vacuum cleaner to the service center because of air leakage and peeling sponge parts. After two weeks, they let me know that because they didn't have the item in stock, they would swap it out for a blue one. I declined this color, and they said they would either replace the part or return the product. We bought the product on August 30th, and within six months, several folks have encountered the same issue with this device. How do we make sure that the new device won't have the same issue? Would there be a charge if this issue happens again once the warranty is over? Given that this issue keeps happening, will we need to continue sending the device to the service center whenever we face an issue down the road? So, if Dyson has other colors available for a device that's only six months old and the user isn't happy with the color, why not just upgrade to a better model? Where can I find customer satisfaction? Do customers come back to purchase from you? You've only made a name for yourself; you deserve a low rating in terms of customer satisfaction. I purchased this product for three family members, and another person encountered the same issue. They'll also send it to the service center, but doubts linger in people's minds. Sending the product back to you until stock arrives is just not feasible. Way to go, Dyson, you're absolutely amazing. There's no such thing as customer satisfaction in this service. I work in the electronics industry too, and at least we don't mistreat customers when products are unavailable. You should take another look at the user procedures.
