BAD SERVICE

On the 18 March 2016 booked my car in for the 2nd time as the engine light was showing. My car has been at the dealer since then to date, on the 22nd the lady that i booked my car with called to let me know that they are still trying to figure out what the problem could be but she will call me on the 23rd after 11:00 to let me know what the finding where. Shes never called me, i called her at around 14:30 to find out whats happening, which again she promised to return my call after 17:00 which am still waiting for that call. I have been without a car for 6days & this is not the first time the car been booked in with the same problem, which i was told was resolved when i collected my car in February 2016. As a paying client with a car that is still new sitting on 47 000km am really upset at the appalling service, how am i suppose to move around with no car for 6 days and right now we approaching the long weekend am i expected again to sit back and wait till the following week. Mercurius Motor Polokwane bad customer service, their booking agents make promises they cant keep and worse you have to do their job and follow up call after call.
