What would be wrong?

you need to take the car back to the place where you had it done and say can you check the rear brakes to make sure they are not binding ,and check around the rear wheels for any thing thats catching , if the brakes are binding its down to poor workman ship , or they did not no how to set the rear brakes,or if you dont wont to takeit back there , you can take it to a renault dealer and book it in for a free health check and they will check it for you , and just mention that , as you said that when you brake theres is a noise , coming from the brakes, hope that helps .
