Pathetic After Sales

I recently bought a car from McCarty Centurion and the sales person was Sandile Gininda.Everything was fine from the begining of the sale,he would call me hundred times a day.I ask him if there is anything he want to disclose before we proceed with the sale.(Nothing)When collecting a car i aksed for the spare key.The Agent told me that the vehicle was less because they did not included a spare key.After a big fight i then involve his Manager Hennie who promised to contact me back with the feedback,not even once he came back to me.After many many calls they decided to pay for my spare key.Now i have another issue with the vehicle license ****.I have been waiting for them to contact me regarding the disk.i then call them again to be told that the disc is there is can come and collect.I asked my colleague who stays in the area to fetch them for me,she said she waited for over 30 minutes while the same sales person was trying to find them.Later he said the disk is not there.this is shocking especially from a reputable dealer like this.I believe they dont need me anymore since well the sale is finish.All i need is to be treated like a customer and with respect.Is that too much to ask? <br>
