Revolting attitude

I've been a Hyundai customer for 2 years now and each time my vehicle was booked in for whatever service I'd get dropped off by their employeed driver to my chosen destination and collected again once my car is ready. So today the driver from the boksburg branch did drop me off at home so I thought he'd come and collect me after the service has been completed. At exactly 16:30 I receive a call from a young Indian lady, I just forgot her name she was informing me that my car is ready so I ask her if there'll be a driver that will be collecting me she said no and I must organise my own transport and I must be there by 16:55. So I explain to her what would previously happen in this sense and I inform her that I wouldn't make it there on time because I wasn't informed to organise transport earlier. I was venting my frustrations to her and she just hung up as I was talking to her, I'm very frustrated that as a client I was not informed about the changes made by the company and that this lady had the audacity to hang up at a client, she was unprofessional, rude and unapologetic.
