Canon EF 24-70mm 2.8 L Lens Not Working

It comes with Lens Hood, Caps.

It shows signs of use. The optics look clean with a few dust specks inside.

The lens started reporting an error with the contacts and no longer works. Prior to that autofocus worked but the zoom extended only between about 28-65mm; it didn”t fully reach 24mm and it didn”t fully reach 70mm.
