Unsatisfactory Service

I was contacted by Motorite regarding a service plan for my vehicle. The consultant who loaded the service plan onto the policy, loaded the service intervals incorrectly. After numerous phone calls and emails to Motorite, they are still not able to rectify THEIR error on the policy after providing the requested information from the manufacturer as per their request. This is absolutely unacceptable. How does a company that provides service plans not know the service intervals for diesel vehicles????
