York Motors - After service poor.

I have bought a Land Rover Discovery at York Motors through Danie. He also sold a unlimited service plan to me. The service plan is through Motorserv. I struggled now for very long to get my Land Rover service, because there is no answer at Motorserv. No feedback on mails. I called Danie, because he promised me that this is a great service plan and asked for help in December. This is already end of February. I talked to him and his answer to me is, it is between me and Motorserv. I feel that he sold the plan to me, and must help with answers. I am very dissapointed in York Motors with their after service. Will never again bought a car there.
