No regard for the customer

I booked in my car at Hyundai Sandton for the radio to be repaired. The Service Advisor assigned to me was Janet Mothoagae. During the day she did not keep in touch with me as indicated in the sms that I received earlier. Needless to say my problem was not solved. In fact I was the one who picked up my phone and called after I had received an sms that my vehicle was now in the wash. How can you wash the car and offer to repair my windscreen chip marks (not what I had brought it in for) without letting me know if you managed to fix the actual problem i.e. the radio?!! I arrived after 3pm to come and collect my car when I arrived Janet was having a nice chat with the other staff and attending to her children instead of attending to customers. They brought my vehicle to the front and she told the gentleman who brought my car to give me the keys. She didnt even take the time to let me know what was wrong with my car and why my problem could not be solved. I got up and asked her if there is anything I should know or sign? She said no and wasted time in getting me the number for the external service provider who is to assist. I am disappointed in Hyundai, little confidence in your brand!
