I returned a V11 vacuum the day after it arrived. I didn’t even open the box as I decided I had acted hastily and I was spending more than I could afford. 
Dyson Canada was supposed to refund the finance company, but they refunded for a different V8 vacuum which I had purchased in 2022. The credit card used for the purchase was no longer valid so this mistaken refund could not be completed. 
However, they have not refunded for the V11 and the finance company is hounding me to pay for a vacuum which I returned. Dyson seems incapable of comprehending this sequence of events and keeps “escalating” it to God knows where, so I’m left spending hours at a time on the phone with a horrible customer support service, trying again and again to straighten this out. 
The level of incompetence is astonishing. 
If anyone knows how to bypass these low level service agents and how to contact someone who can actually help me, I would be very very grateful for your help.
