I purchased two vehicles with Ziegler Lincolnwood ...

I purchased two vehicles with Ziegler Lincolnwood in November and December 2019, both vehicles have had no issues and when I was purchasing the vehicles, service from the salesman Ray Jando was superior to previous places I have visited, made me and my entire family felt welcomed there, where everything starts to fall of is when I try to schedule an appointment to have my brake pads and rotors changed, I have called multiple times over the course of a month and it always lead to the same ending, I get sent to voice mail of some David Fernandez (I m not super sure what his name is that s what I heard each time it went to voice mail. My main issue is me buying two cars from the dealership and my understanding is that they provide better services with a smile than other dealerships or mechanic shops. I have not seen this at all and am hoping this can change for me. I still plan to call and schedule an appointment for my car but if this keeps ending the same, sadly they will lose my patronage
