bad service from the word go!

i really do not know if this is racial related or what, the people that i am dealing with at we buy cars midstream regarding my deal are very unprofessional and rude, it seems as if they are doing me a favour for buying that car, i do not think that's the same ethics the owner ( Dirk van der Walt ) of this company stated his business based on. where is the business principle? where is the mindset of if this business was mine? yesterday i drove all the way to midstream after work, and Sadia Khan was unacceptably rude from the word go as i entered her office * i knocked and she rudely said you knock first .. like what F***** Mind you these people have all my documents and i then called to tell her that i in a possession of my certified ID Copy. she still could not help because i did not have a copy of my ID. so yesterday i failed to take delivery of the car , This process took almost 7+ days to be completed going back and forth. take your guys to a customer service training
