No one called back

My name is Ashley, I called KIA Motors Sandton to book for a car service on Monday [30 November]. I spoke to a switchboard operator who tried to transfer me to the service department but the line was busy, she then told me she will take my details and someone from the service department will call me back. I waited the whole day for someone to call me back (No one from KIA Motors called). On Tuesday(1 December) I called again and I spoke to the same lady who promised me that someone will call me back, I told her that no one called - she then told me she will get someone to call me back because the line was still busy guess what no one called. Today it's Thursday and still waiting for someone to call me back. The Kilo for my car was 120 000 on Monday and now I am on 121 164. if I don't service this car by the end of this week I will lose my service plan. <br> <br> If this is not attended to I will escalate this with Liquid Capital who handle my service plan.<br> <br> Regards<br> Ashley
