Customer service shocking

With every encounter I have had with KIA I have found them unprofessional and the customer service is shocking. Today I submitted my car for a service at the KIA east rand, boksburg. Last week when I phoned to make the appointment I was told that I can bring my car from 7am -9am and was told a driver would be provided to take me to work. when I arrived at 07h10 this morning I had to wait 50min before someone could take me to work, even though their were KIA staff already in the building. I was then told that the "drivers" only be at work at 08h00. I work at the bank and need to be at work at 08h00 hence why I arrived early to drop my car off. I am disgusted with the service I have received. Management should have gotten involved and assisted their irate clients. When I arrived at work I phoned KIA to inform them that my husband could only fetch me at 17h15 which means that I could be slightly late. I was told that they close at 17h30 but they will wait till 17h35 but no longer. Am I not a client of KIA? don't I deserve good customer service?
