Innovation Group and Toyota

Hello Peter I have problem with Innovation and Toyota, before my car got ****** I took my car for service for 45000KM service and I was told that this is my last service because I only had 3 service plan. I took an extended service plan with Innovation Group and later cancelled it, only to find out that the service plan was already paid by Wesbank in advance up to 80000KM right now I am paying for that service plan because they saying whether I used the service plan or not I must still pay for it. Why did they let me pay for another service yet Wesbank has already paid in advance? Why did they say my service plan was exhausted I can no longer service my after 450000KM. Right now I am paying for installment of service plan which I was told it was exhausted before using it.
