Disappointed

Hi. I bought a Toyota Avanza from this dealership in July. I was told by the sales persons Kevin that the van was just serviced however when I look at the service book the vehicle was serviced 23400km before the current service. I am having a problem with the seat which the company is well aware off. I have no response ever since I email and laid a complaint. Please can I be contacted to explain in full. I received a totally rude email from salesman Kevin and thereafter no acknowledgment of my emails. I have received no calls from them. When I purchased the vehicle I had to license the vehicle all on my own and payment was reimbursed to me weeks after. Please call me ********** 826.
