bad service

I have a service plan with these people and im paying 219 every month, the latest one was till 80 000 km of which i took my car in in august for that 80000 km. when the 90000 km reached i then took my car in on friday at freeway toyota for service and was called back to be told that it has expired already but the payment went through for september. No one called me from the call centre to renew my service plan and i thought it expires on the 90000 km.. I then called in 2 days befor i took the car in to make sure and the lady assisted me said the last one is 90000 km.. I had to pay 1400 cash of which i did and now i call in to extend it they telling me about the 3 months waiting period of which im not willing to do... these people are ***********..i wont wait another 3 months.. i just want this sorted now
