Ford! - Great product; pity about the service

I drive a Ford Fiesta purchased new from Halfway Ford in Waterfall, KZN in November 2017. Their service has been poor - taken 5 visits for them to fix the aircon which hasn't functioned properly from new. Firstly the service adviser tried to deny the problem. I had to complain to the then dealer principal to get some action. Now finally after 18 months they say they've found the fault. I am now driving around in hot weather waiting for the parts to arrive. Everything from the service to the sales process is poor. Every time people there don't do their jobs one needs to complain to someone higher up or the manufacturer's customer service dept to get action. They are tiring and frustrating to deal with. Much as I like the car my next purchase will be of another brand.
