Bad service

I am very upset with Ford. I took my car for his 70 000km service yesterday. I receive a call from BB Auto in Polokwane to inform me that my service plan lapsed. I told them how can that be no one inform me anything and I am under the impression that I still have a service plan until 90 000km. They told me no it is 90 000 or the date. I feel very upset because the people from the service plan just told the lady from BB Auto it is not heir job to let us know when our service plan will be finish. My question is why will other companies then tell you each and every time when you take your car for its service you have so many services left and make sure you bring your car in before then but FORD can't do that it is not their job! I will never in my live buy a Ford again and I am going to tell everyone about this experience it is BAD SERVICE!!!! I paid all that money to have a service plan now that my car must get his major service they tell me it has lapsed if they informed me I would have taken it in for the service why did I pay all that money to only have small services and now that it is time for his major service they are telling me this and I must pay R8440.24!!!! I did not service my car and have to drive it without any service because FORD see it is not their JOB to let customers know their service plans are almost finish. All I can say is I am VERY UPSET about this!
