Poor Service at Jeep Constantia Kloof

I booked my car for the 60 000 service at Jeep Constantia Kloof. On the day of service I was told that I must pay R9 000,00 because my motor plan expired in October 2018. I perplexed because I did not have accurate dates but I had to do something. I did what the staff of Jeep Constantia should have done before the date of service. I called Jeep Client service and they requested for the Vin number and informed that my vehicle was still under service plan. I had to stop doing my day work and called, this is not fair. That was the worst service ever.
