Sold me incorrect service plan

I bought a 2011 Toyota Aygo from a Toyota dealership in Feb 2015 without a service plan. In April 2015 I was called by a consultant of Innovation group affiliated with Toyota and asked me if I am interested in a service plan that would cover my 30 000-60 000km Services with Toyota. The Aygo was 2nd hand and had only 14000km on the odo when we bought it so I agreed to this. This year I booked it in for the first service on this plan and was told by Toyota that the service plan I had was incorrect and should have been for the 60***0km as the vehicle had allready had 3 annual services prior per year (which I was not aware of since the kilo's were so low). And no one from Innovation can explain this to me, I get voicemail when I call and the one consultant who did call instead of fixing my plan tried to sell me a maintenance plan?!!! Next step is to take my complaint to Toyota.
