Hoodwinked and in total shock with Suzuki

I am in total disbelief at how Suzuki hoodwink their customers. Having serviced my race car and my own car I should have checked but I thought I could trust such a huge car dealership. 2 services and not once was the air or oil filter changed. This was discovered when I took it to a mechanic well known to me and the lack of service may have caused damage to the vehicle!!! Is this how you make more money !!!
