Bad Aftersales

Very disappointed in the after sales of the Renault Fourways Dealership. I bought my second hand i20 from them in the middle of April this year, a few days after having the car I noticed the same noise that was in the car when we test drove it (Was told the car would go for a service and the noise would be fixed, aswell as the scratch mark on the bumper would be fixed) before handing the car over to me. None of this was done, 4 months later and I still dont have the spare keys, no one from the dealership, including the dealer principal is returning my calls or sorting this out. the cars brakes, shocks, and clutch should of all been done in this so called service which shows it was never done. This has been such an unpleasant experience to say the least. If someone from the branch can call me with regards to when they will fix they car like they said they would initially and handover the spare keys! the only time you hear from them is if you the one constantly calling, its become a full time job just calling non stop leaving messages! Very disappointed in the service and the after sales experience I keep having to deal with.
