Overheating Grand cherokee

My car started overheating in the morning on monday the 04-12-2017 i call grand central midrand as they’re one’s that fixed it in may this year while it was doing the same Arnold suggested i call roadside assistance which i did and they arranged for a tow truck to come pick up my car. After the tow truck took my car i ask Arnold from grand central so now how do i go home since this is a mechanical breakdown and it is inconvenience me? He told they don’t have a courtesy car i must call roadside, well i did call them and they told me there’s a process to be followed they can only advise after the car is diagnosed and they don’t hire a courtesy car if where the car broke down is within 100 km from the dealer. I told them I don’t want a car to go to the dealer but to go home as i am in midrand and i have to go home after work, well they just told me they’ll get back to me but they didn’t. Today Tuesday 05-12-2017 the whole morning I didn’t get any feed back around 12 I decided to call the call center which they also didn’t have feed back but they will call grand central to ask for feed back, 2 hours later no feed back i call again to ask what’s happening i spoke to a gentleman man by the name of Katlego he said i must give him my details so he can check and he will ask Arnold then revert to me. The feed back i got an hour later was that they’ll have to change water pump and i might get my car friday so i ask d how do i go to work since i dont have a car? I was told same thing about the police that stated that if the customer is with in 100 km from the dealer no courtesy car can be arranged so now the whole week i must stuck. How stupid is this policy., i mean I don’t care about being near to the dealer i am talking about traveling from centurion to midrand to work now that my car broke down for the second time this year after they say they fixed it.. I am really disappointed and ****ed with the service also that one have to call again nad again to get feedback of you don’t adk nobody call especially at grand central.. I wouldn’t recommend to anyone. The service is bad.. if i have to compare to other dealers i drove the year before last a manual 320i when i stuck because of clutch BMW sent a tow truck and within an hour they arranged a courtesy car for 5 days while mine is getting fixed but jeep no you have to make plans while the car is still under maintenance plan and you paying for it that’s pathetic..
