  We study the Klein-Gordon (KG) oscillator with a Cornell-type scalar
confinement in (2+1)-dimensional G\"{u}rses space-time backgrounds and report
their exact solutions. The effect of the vorticity parameter $\Omega$ on the
energy levels is found to yield some interesting features like; energy
levels-crossings, partial clustering of positive and negative energy levels,
and shifting the energy gap upwards or downwards. Such confined KG-oscillators
are also studied in a general deformed G\"{u}rses space-time background.
Moreover, we consider the confined-deformed KG-oscillator from a
(2+1)-dimensional G\"{u}rses to G\"{u}rses and pseudo-G\"{u}rses space-time
backgrounds. The resulting confined-deformed KG-oscillators are found to admit
invariance and isospectrality with each other
