Horrible service

I bought a car about a year ago from the Hyundai Alberton branch and they forgot to give me a service book and when i took my car for service for the first time i asked if they can send the service book to the dealership that i took my car to and their response was no i must come fetch it myself and i explained to them that i stay far and i won't be able to fetch it. I had to tell them that i will not waste my petrol and go there when this is due to their negligence from beginning, they must make the necessary arrangements to get this service book to me and they eventually agreed and said they will courier it to me but i have been calling them ever since almost every week for about 2 months about the delivery of this service book but till today i do not have it. What is even more annoying is that the person i was dealing with doesn't even want to take my calls anymore and i keep leaving messages for her but she doesn't even have the decency to get back to me.
