Non Compliance to complaint of service

I booked my vehicle in at Kia Wonderwaters for service and replacement of front brake pads. At 12:30 I receive a call from Anton, stating that they do not have the parts and can not get it before Friday. They knew from 25Sept that my vehicle was coming for brake pads. He states that it's not his problem and that he does not order parts. It's my problem to bring the vehicle back on Friday.<br> I call Head office and in the end they take a message for Mandy, she is said to be the PA to the CEO. Obviously I do not get a call back from her. I can also not get any email address except the customer care one.<br> Please contact me asap, I have problems every time I take my vehicle for service at Kia. Thank You.
