Unused Mac Pro Apple Care registration :(
I own a 13 inch Macbook Pro 2017 with Touch Bar whose standard warranty is about to expire. In an urgency to extend the warranty, I purchased Apple Care from an online re-seller which arrived the next day. When I tried to register my device with the extended warranty, it didn't work. I tried getting help from the Apple support who informed me that the registration number is for a 15 inch MacBook. I re-looked at the Apple Care packing and to my horror realized that I had purchased Apple Care for a Mac Pro and not a MacBook Pro 😢. The re-seller would not accept return and I don't see a point in asking for it when the mistake is from my end.
I am checking what options do I have to dispose the unused warranty other than giving it away for free and suffer a loss of X dollars. If anyone could help me out with suggestions, I would be grateful.
