MacBook Air replacement return confusion

I have a 2019 MacBook Air (A1932) and I’ve been renewing my AppleCare+ every year since purchase in 2018.

I’ve had it serviced for replacement battery, done a hard reset, and my most recent visit an issue with my keyboard & slow response. It still works but very slow.

When they ran the diagnostic, the service advisor said it’s considered a “vintage” & they are no longer able to do repairs in store or with authorized dealers since they don’t have the parts.

I was redirected to call Support & did so in store in which they upgraded my laptop. However, when I asked if I needed to send my current laptop back, the Sr. Advisor said no, it’s mine & I keep it. That was basically it with the call & she confirmed I’d be receiving my laptop in up to 14 days.

I decided to call back later in the day because I didn’t get a confirmation or anything so I wanted to make sure. The new advisor is now telling me I need to ship back my laptop to receive the new one but the other advisor said I didn’t have to. I’m feeling a little upset since I was already told I can keep my laptop originally & now I have to go 2 weeks without any laptop.

What would you do in this situation if you were told one thing but then it’s another? Is this process accurate?
