Narrative:

We were on the paradise four arrival to runway 25L at 270 KTS. Shortly after passing konzl, ATC issued the following clearance: 'air carrier xyz change runway to runway 24R via the mitts arrival, go direct to snrkl.' I read back the clearance as stated. I activated the secondary flight plan which was loaded with runway 24R/paradise 4 arrival. I asked first officer if he had found snrkl and he said yes and immediately put snrkl in his FMGC. We were going direct to snrkl and descending to 12000 ft. I was changing to the runway 24R transition. ATC issued the following: 'air carrier xyz cleared ILS runway 25L via paradise four arrival.' I read back the clearance and asked approach to confirm the runway because we had just been cleared for runway 24R via mitts arrival. Approach said that was for a company aircraft, air carrier xyz was cleared for the approach to runway 25L via paradise four arrival. We turned left to re-intercept the paradise four arrival between rifft and pdz. We had been descending to 12000 ft. As we turned back to intercept the paradise four arrival, we were east of rifft intersection at 13500 ft. ATC advised us we should be at 14000 ft. I acknowledged we were correcting the altitude. At pdz ATC cleared us direct arnes maintain 10000 ft and cleared approach runway 25L after suzzi. The approach was as normal as can be expected for lax after arnes. There was an air carrier xya on the frequency who used runway 24R, but I don't know what his clrncs were. The first officer called socal approach after we landed. That individual acknowledged there was some miscom with us. His statement of miscom was, incorrect clearance issue, readback, or wrong aircraft readback. He also said there was no conflict created, saw no problem and saw no reason for any paperwork being filed. The first officer and I are 99% sure we received a clearance to runway 24R and that I read back the clearance to runway 24R with no correction from ATC.
