The poorest service by far

I booked my 2013 Ford Kuga in at Ford Barloworld Alberton on 5 jan 2015 with electrical problems. It was there for 4 days and on the Thursday 8 jan 2015 i requested a courtesy vehicle because i couldn't make another plan to get to work and they told me i must come and fetch the car and they can't seem to get it fixed. I was instructed to take it to the branch where i bought it, which was Ford the glen. I went on the Monday 12 jan 2015 and spoke to the Service Manager Barry. He told me that they haven't got courtesy vehicles and he can't understand why Barloworld referred me to them and told me they should've handled the matter but he will phone me as soon as he has got a courtesy vehicle. I waited a week and phoned them as i haven't heard anything from them. Barry told me that they still haven't got any courtesy vehicles. Another week passed and i phoned Barry again and really lost my temper because i am driving a faulty car and possibly is causing more damage by driving it in that condition. Barry told me that it wasn't Ford the Glen responsability to supply customers with courtesy vehicles. I reported this to Ford SA and it's been 7 weeks and my car is still faulty!!
