Un called for harasment

I went onto the Suzuki Website to attempt to make a booking to do a 30000km service for my Suzuki 20/05/2024 I completed the online form with all required details. On completion, the following page says that I will be contacted within 48 hours by Suzuki to make an appointment. I did not want to wait the 48 hours. I then immediately called my nearest service centre and made a booking for 21/05/2024. While busy on the phone, my phone went crazy. As soon as I had completed my booking call, I started answering call after call after call from different service centres, all wanting to sell a car to me. I HATE THIS!!!!!!!!!!! I wanted a service, not multiple calls trying to sell me a car. This is false/misleading nonsense from Suzuki. I don't want another car, I only want to service a car. Don't give my service information to your car sales department and have them harass me with dozens of calls.
