Disgusting Service manager

Mark Tomas Service manager, needs to learn how to speak to people and have a little more compassion. My car was booked in for airbag change and actuator replacement, when getting there they tell us it must be diagnosed first, these things were not communicated to us so asking us for another R1000 FOR DIAGNOSES IS A BIT MUCH WITH NO WARNING... He refused first to come out and speak to me, eventually he does come, I mean I moved mountains to be there today and it cost me a days work, my wife stranded at work for the day, my kids had to get a lift in to school.... He speaks to me hears me out and proceeds to say "If you not going to pay the fee and do the job, then take your key and go." is this man feeling okay, who does he think he is to speak to people like that... Take ownership for miscommunication man. I will never return to this branch only due to this man, I am no-ones child there.
