You already did the oil and hammer method. Try to hammer harder!!!!
It's junk anyhow.....

If that dont work, use an angle grinder and cut it off. Thats a no
brainer....

Of course you'll have to buy a new one, but it dont have to be the
locking type unless you live in a real high crime area. The non-lock
type are about $5.

I bought an old used pickup truck a few months ago that has a trailer hitch

open so I can remove the towbar/ball (or whatever that is called).
