BAD CUSTOMER SERVICE AND UNPROFESSIONAL SALES AGENT

I purchased my third Ford Fiesta in January. I checked for the car online and was happy with the price. Once contacted by the sales agent at CMH Kempster Ford Pretoria I arranged for the car to be brought for a test drive. The car (a demo) which was used about a year I guess, was brought to my office. It arrived filthy. It was sooo dusty and the seats were dirty. I was assured by the driver that they will wash it before I take it. Once I got to the sales office I was made to wait 2 hours before I could proceed with the process in the finance office. Everything felt rushed and the sales agent mentioned that they want to get it off the floor since its 31 Jan. Paperwork took a while but everything was briefly explained. Once I took the car, it looked clean, but when I drove it off it was still very dusty. I told the sales agent who wanted me to drive back to PTA from JHB for that. Then upon assessing my car at Glasfit, we realised my license disk had expired in December(it was Feb already). Only once I called the sales agent did he say he'll send it the following day. (which he sent 2 days later, along with my spare key). Then three days later he calls for me to URGENTLY send my settlement letter from the bank, two weeks after the sale. They need it on the day, immediately. I realised my bank never sent it to me so had to run around to get it. Another 5 days later they want a certified letter stating that I give permission to hand over the account from one bank to the other. Now all these letters they wanted ON THE DAY, IMMEDIATELY. I still haven't received my service book as requested and I still don't have the cars manual. The agent keeps promising to send it but IM STILL WAITING. This is so unprofessional and the first time I've experienced such unprofessional sales and customer service from Ford. I love the cars, that's why I went back three times. But the customer service makes me reconsider.
