Newly purchased magic band linked to someone else

So I visited WDW on September 4th and bought a magic band at their all star resort. It was on the fritz all day and I figured I’d debug it later, might as well just get a card pass and enjoy the day rather than troubleshoot tech.

I’m returning in November for another visit so I called customer service and it turns out this magic band is linked to some random Canadian dude, confirmed by Disney customer support phone line just now. They told me I need to go to guest relations at the park to see if I can get a refund/replacement.

So… what?? How on earth did I buy a magic band new at their resort and it’s locked to someone else. And they’re powerless to fix it. Feels like a mouse scam, definitely wouldn’t recommend getting one if their in store product is not secure…

Has anyone experienced this and have a workaround? (I tried factory reset, also)
