Bests & Worsts Reviews from Amazon

I purchased this as a Christmas gift for our family. We had it for a couple weeks before opening the box on Christmas, then put it together soon after. We used it in very light duty (vacuuming underneath kitchen table) 2-3 times across about a weeklong period. The next time we tried using it, the motor began to pulse. We then emptied the trap and cleaned the filter as instructed. After taking off all the attachments and looking in the debris trap and filter area, we found that only with the presence of the filter were we experiencing the pulsing issue. After calling Dyson's customer support line and checking all the nooks and crannies they suggested in order to look for blockages and coming up empty, they decided to send us a tool that would enable separating the filter/debris trap/venturi assembly from the handle/motor assembly in order to support us looking for blockages at the entry of the motor. After a 7+ day shipment, we immediately used the tool to separate the two assemblies and found no blockage. Immediately that evening, we called Dyson's customer service again, and the next suggestion was to send us a new filter. After another 7 day shipment, we immediately replaced the filter, and we still experienced the pulsing issue. Calling Dyson's customer service line again, on hold for at least an hour, they indicated that I needed to send the vacuum to the Dyson repair center (for us to pay for shipping) – no claim number was provided to me and I did not feel comfortable sending it to the repair department without a claim number. When I asked for a replacement, they indicated that I would need to return the vacuum through Amazon.com since that was the retailer I purchased the item through. When checking into a return to Amazon, we found that the return window had just closed a few days earlier because of the time that had surpassed since the purchase. When calling Dyson again immediately the next day to ask for help on our situation, Dyson was unapologetic, so I asked to speak with the manager and then got put on a long hold again, then I was told that the manager would call me back. Days later I still have not received a call. This entire situation is unacceptable.
