UNHAPPY ABOUT SERVICE FROM NISSAN EDENVALE

I am extremely disappointed with the treatment we got from Nissan Edenvale,from the 18th August we took our car to them because it was overheating until today the matter is still not resolved and we had to use taxis they could not even offer us a loan car ,they would take car for a week and give it back saying its fixed in 2 days time problem starts again and worse ,the last straw is us calling on a tow truck on the 05th September because the car was over heating in the freeway 3 days after collecting from Nissan ,we are now using taxis carrying our valuables to JHB taxi ranks praying everyday we dont get ****** while Nissan Edenvale has our car ,worse part the car was bought at that dealer even for service it is serviced by them.All we need is our car to be fixed if not in time its but we need a loan car because it is now 2 weeks they have our car .Their communication is worse you will need on calling them for follow up
