Need help on how to go about my situation
So for context I ordered an ebike off alibaba and after a 100 day delay it finally arrived just for it to be the wrong model, 17/14" wheels instead of the 19/17" wheels. Basically they promised me the 19"/17" model and somehow accidentally sent the wrong one so I decided to file a dispute asking for a full refund. After going back and fourth with them offering $150 compensation then $500 then $600 and me not budging they finally sent me this message
"Hi
We truly value our cooperation with you. After discussing with our management, we come up with this special‑solution for you as a gesture of goodwill.
We will ship a brand‑new 19/17 black‑orange motorcycle directly from China.
You do not need to return the existing 17/14 bike, we will give it to you for free. This is a special goodwill offer only for you, not our standard policy.
If you accept this solution, please kindly cancel your refund application, and we will arrange shipment for you right away.
Should you have future purchasing needs, feel free to reach out, we will offer you our best possible price."
I was wondering what the safest way to approach this would be, as this offer does sound incredible but of course they tried to scam me once so I'm sure they wouldn't mind doing it again.
