If the service tech can't replicate the issue they won't be able to charge the job as warranty work. There is a chance your car didn't chirp during their test. Since I've switched to Shell 91 the crickets have gone away. I have heard from other owners on this forum and read in magazine long term tests that the crickets come back even after fuel pump replacements. Most gas stations have shared fuel fillers so the first few litres of gas you get will probably be low octane stuff with ethanol in it so you still might get crickets.

It's not just ethanol content, and even the "fixed" pump still has crickets from time to time.
I've had multiple tanks of Shell 91 that chirped, and multiple tanks of Petro 94 that didn't. I find the colour of my shirt has as much influence on if it chirps or not as the fuel.
