Airbus do have a stall recovery procedure, its in the QRH as are procedures for ADR failure etc. These are all things that are trained or should be. If your confused about pulling or pushing in a stall then you shouldn't be doing the job. Its basic.
Maybe they did not recognise they were in a stall or were confused/distracted by the discrepancy in airspeed. Yet again it raises questions about selection and training.
