Misleading information

I joined the Innovation service plan in 2015 and was told that I was covered until 60000km. Little did I know that I would get a nasty surprise when I took my car for the 60000 service, only to be told to pay in cash because my service plan has expired. When I called to find out, I was told that I'm only covered until 45000 but the premium continues to deduct afterwards. Why was I not given this info when I joined? Being the big company they are, why was I at least not contacted after the 45000 service and told that I'm no longer covered so I could make other plans on time? It is very disappointing to see that they sell their products by giving misleading information. Once they've got your money, you are left to suffer alone!
