All models have ABS, though on the ones with ESP, the two systems share some of the same sensors. They may well operate from the same controller as you were originally told. If your ABS is not working, then you should have the warning light on the dash, though it's not unknown for people to 'fix' an ABS fault by removing the bulb.
The best way to test the ABS is to find an empty road or car park with a loose surface (e.g. gravel.) Get the car up to a reasonable speed and then slam on the brakes. You should feel a rumbling or grating sensation through the brake pedal as the ABS activates and the wheels should not lock. If they do, then you have a fault. If you can't find a gravel surface, then a wet tarmac one will do, but you'll have to brake much harder.
Theoretically at least, a car with defective ABS is not as safe as one that was designed without it, and for this reason, faulty ABS should cause the car to fail an MOT.
If ABS does work but ESP doesn't, it sounds like they either replaced the computer with the wrong one (i.e. one that doesn't have ESP) or the ABS computer needs reprogramming on Clip. You'd probably have to consult a Renault dealer or specialist to find out for sure.
