Leather beautify

I have two chesterfield chairs that looked nasty. The glazing or what ever was rubbed on them has now worn off, not everywhere, but enought to make me crazy. I need to make clear these are not Hancock & Moore chairs, but they were in same price range.
Ignorance was not bliss. They were purchased online from Mayfield out of Hickory , NC. Thus far, the seller has told me they were not responsible when the bun feet started falling off after about a year, same response when I called about the flat cushion cores. The chairs are a perfect fit for the room I use them in, so I need advice on how to beautify them. Can they be reglazed?
Thanks for any and all help and no I can not pitch them.
