Narrative:

Aircraft 1 was cleared for visual approach 18R with reported traffic as aircraft 2 flying VFR, and aircraft 3 who was cleared (amazingly) to 18L. The controller and all other aircraft were 'communication jamming' the radio frequency and we received a TCASII RA to climb at 1000 FPM to avoid the aircraft 3. We saw aircraft 2, we did not see aircraft 3. We should have been turning south to intercept the 18R extended centerline and avoid aircraft #3 but we could not turn south because the controller had cleared the aircraft #2 to cross over and above our flight path to intercept 18L. In other words, the RA to climb, our clearance to turn south to runway 18R and the aircraft #2 in our way made it so we had to climb straight ahead (easterly). This caused us to fly through both 18R and 18L ctrlines before we could turn back, now behind and practically co-altitude with aircraft #2. Meanwhile, we could not get a word in on the radio frequency to notify approach that we had a TCASII RA. We climbed and we couldn't turn to final! Then we had to quickly go to tower. We never told the approach controller and he, apparently, never saw our altitude climb or our flight path discrepancy.

Title: ACR PLT CAUGHT BTWN 2 ACFT ON EITHER SIDE CANNOT TURN INBOUND UNTIL AFTER XING THROUGH FINAL APCH COURSE. RECEIVES TCASII RA.

Narrative: ACFT 1 WAS CLRED FOR VISUAL APCH 18R WITH RPTED TFC AS ACFT 2 FLYING VFR, AND ACFT 3 WHO WAS CLRED (AMAZINGLY) TO 18L. THE CTLR AND ALL OTHER ACFT WERE 'COM JAMMING' THE RADIO FREQ AND WE RECEIVED A TCASII RA TO CLB AT 1000 FPM TO AVOID THE ACFT 3. WE SAW ACFT 2, WE DID NOT SEE ACFT 3. WE SHOULD HAVE BEEN TURNING S TO INTERCEPT THE 18R EXTENDED CTRLINE AND AVOID ACFT #3 BUT WE COULD NOT TURN S BECAUSE THE CTLR HAD CLRED THE ACFT #2 TO CROSS OVER AND ABOVE OUR FLT PATH TO INTERCEPT 18L. IN OTHER WORDS, THE RA TO CLB, OUR CLRNC TO TURN S TO RWY 18R AND THE ACFT #2 IN OUR WAY MADE IT SO WE HAD TO CLB STRAIGHT AHEAD (EASTERLY). THIS CAUSED US TO FLY THROUGH BOTH 18R AND 18L CTRLINES BEFORE WE COULD TURN BACK, NOW BEHIND AND PRACTICALLY CO-ALT WITH ACFT #2. MEANWHILE, WE COULD NOT GET A WORD IN ON THE RADIO FREQ TO NOTIFY APCH THAT WE HAD A TCASII RA. WE CLBED AND WE COULDN'T TURN TO FINAL! THEN WE HAD TO QUICKLY GO TO TWR. WE NEVER TOLD THE APCH CTLR AND HE, APPARENTLY, NEVER SAW OUR ALT CLB OR OUR FLT PATH DISCREPANCY.
