Francious bad attitude/ Horrible service delivery

some time last week of Nov i took my car in because i had a error complaing about light controls, brake lights. dipped beam and other lighting functions being faulty. the vehicle urged me to stop and check whats wrong. i took it in and to my shock met Francouis who was so unfriendly and looked down while talking to me. he had such a stinking attitude helping me showing no interest in helping me. i wonder why would someone have a bad day if its only 8 am. The car was never test driven. This francoius said they didnt find anything wrong even if i found it. does it mean im better at detecting faults on a BMW than they can? the minute i drove off there problem was there just at the gate of the glen BMW. i then took it back and they tested all of a sudden they found the fault and Francious said he will order the part and call me. 2 weeks and days went by without them calling me. my husband called and thats when they only gave me a date. Francious is not interested in his job. And the technicians are useless . I took the car in and now he tells my husband he was never given the job card whereelse i saw the technician driving my car in. now my car is not fixed. i dont have a car to drive to work. what did i do to deserve this kind of treatment? i never received such at alberante ever sicnce i owed bmw cars... this dealership is useless.
