Narrative:
I was working local. Aircraft X was tagged for runway 20C; lined up on runway 20L in front of another aircraft. Aircraft X was lost in between the frequency. When I finally got him I gave him a 250 degree turn to join the runway 20C final to keep aircraft Y from running up his tail end. Aircraft Y said he was looking for him; but never had him. Aircraft X said he had been cleared for the left instead of the center. Both were IFR. I told my tower in charge controller in charge. I feel that no action was taken to report this due to the ATC staffing crisis and we can't afford to lose anyone to de-certification.
