hyundai strijdom park ..car breaking down after car serving

Thursday 31 October 2019 took my car a Hyundai accent hatch A/T for 75 000 km service at the Hyundai Strijdom park in Ransburg because it is closer to work and my second time to service it there , during the day I had received a call from the service operator who assisted me when leaving the car at the dealership to inform me that my car isn't responding to them diagnosing it .he informed me about wiring fees that I order for them to get to root of the problem they must change it I informed him that I can not afford to pay that much as I have not budgeted that he must leave it and ill fix it when I have the funds and just do the service only and nothing else

at 17h20 I arrived at the dealership waiting to collect the vehicle he initially assisted me and also informed me that my brake lights are not working which was a surprise to me as the brake lights were working, then I signed the forms for the service invoice handed me the car keys and walked me to the car said our good byes started the car as was leaving the dealership its drove just fine

stopped at the first traffic light just after the dealership then car just slowly lost power when I accelerated the vehicle couldn't accelerate I then looed at the dash warning light there appeared an engine orange light I pressed hazard light controlling the car until it stopped itself on the N1 south bypass opposite the dealer immediately contacted the dealership they sent two gentlemen who came to check on the car they could find the fault and the car could not start waited as the were checking and we had to call my insurance to come tow the car back to the dealer at around 20h15 pm that Thursday evening

Friday I was supposed to travel to Limpopo for marriage ceremony for my brother I needed the car to do that I was in touch with them on Friday they told me that they have not found what is fault with car I could electrical since am using gears manually to move from D to R and it could have happened at any time and requested to strip the car wiring as so they can get the car to start which they failed to do all day informing me I can not get the vehicle all day that Friday I had to make alternative arrangements to travel north since am carless with a taxi and luggage today it is Monday November 4th I call the dealership in the morning they tried to put me through with the service operator with no luck to an extent where the call cut no one has given feedback until now they still in possession of the vehicle

all I need is my vehicle as it was when left at the dealer I regret taking the car for the service because of this experience and service received am and not receiving feedback from the service provider is irritating to say the least
