Expiry of Service Plan.

I bought the vehicle in December 2012 from Hyundai Alberton.<br> Was informed today that the maintenance plan expired in October this year. This is unacceptable as I only bought the car in December 2012 and it went for it's first service in December 2013. It is due for it's third service next month, and now I have no service plan. I was never informed that the service plan was taken out in October. My vehicle only has 27000km on, now I already have to pay for a service. I have contacted the dealer and Liquid Vehicle Finance, no one wants to assist.
