Extended service plan

I took out an extended service plan for up to 120000 km. Now Mitsubishi does not know anything about that. I had to phone Liquid Capital and apparently is only up to 100 000km. Why 100 000km if Mitsubishi only standard comes out with a 90 000km service plan. It was suggested that there was a typing error but I should ask for a copy of my savings plan with my dealer. Now I find out Mitsubishi Brooklyn has closed down and no one knows where I can get these documents. Head office unable to help me. This is totally unacceptable. You pay a lot of money to buy a car, now Mitsubishi knows nothing and I have to deal with Liquid Capital and SA warranties who I did not buy the car from or knew I bought anything from them? No one knows anything and just apparently do not care. I am very upset that I had to spend my entire day to phone 20 people and still no answers. <br> I need answers please.
