Bad Service

This is an on going battle with this dealership! I have a Renault Clio according to the dealership.... a very old one. Booked it in to search for a fault, rented myself a car to travel to work and back. After a week with no response from them they phoned to say that the car was fixed and i could pick it and pay. A huge bill was paid, drove home stopped to open the garage door and the car could not start again. I phoned the service manager that told me they would pick me up and drop me at work, time confirmed for 06h30 the next morning. As a teacher i need to be there at 07h15, the driver only got to me after a lot of calls at 08h00 needles to say that i had to put in unpaid leave. They gave a car to go to work and another 3 days past, a key was to be orderd, as well as a few other stuff that needed attention, the key came after 14 days and it was wrongly ordered once again i had to make a plan because my car left me beside the road after another 14 days the new key was coded, but still the other repairs have not been done parts not ordered yet, since end January! This is bad service par excellance you can leave a million messages nobody ever comes back to you ever!
