Very unhappy customer

On the 8th December 2023 I took my vheical in for its 130 000kms service I was met by a gentleman who assisted me very well and provided excellent service unlike previous visits. I was called and told that my vheical will be parked at security as they will be closed by the time I get there. I collected my vheical at around 6pm and as I drove it for less than 1 kilometer the management light came on and vheical rev started going high and low. The next day I called and spoke to the service manager regarding the matter he took my details and advised that he will call me back as they are fully booked. I need to know who is going to compensate me for transport arrangements that I'm currently using as I'm traveling to howick daily. Also I need to know who is going to be held accountable for this damages as my vheical was in perfect working condition without and engin faults. I was also looking to purchase a new vheical from Key Delta but I think I will look else where. I hope this can sorted out by someone competent enough. Thanks Devin moonsamy 079 460 3933 np 149 768
