PATHETIC SERVICE AT RENAULT

I would like to lodge a complaint at Renault Kempton Park. My car broke down and has been with them for over a month now. On Tuesday i received a message that all parts have been received including the one that they said was not available in the country and they promised that i would receive the car before the end of the week. On the quote they wrote that labour would be 2 hours. Yesterday they sent me a message that all parts have been replaced, in the morning they will refill the coolant and bleed the cooling system.

I followed up around 2pm wanting to know when can i fetch my car and was told that they were bleeding the cooling system. I can see on my app that the car has been making trips since this morning at 9h50 and their trip was an hour. There after its been making 40 minutes trips and they are telling me that they are testing it. It has been parked for more than 30 minutes in Boksburg and im not sure how are they testing it when its parked. It seems like they are now using it do to their erands. I guess my mistake was to send it with a full tank and they want to use it all up.
