Toyota Freeway is a *******

I'm not happy with the service Toyota Freeway offered. I took my car there for a major service and had an engine light on the car. I disclosed the faults on my car and was advised that they'll have to diagnose it first which made sense.

Now the service advisor, confirmed the amount I had to pay for both the major service as well as the thermostat. Upon fetching my car, It did not have the engine light, but as soon as I switched the car off and back on, the engine light came back on. I contacted Marvin/Bongani to inform him about the problem not being sorted, and advised that he'll give me a call later, Which he didn't so I had to call him again since he was now ignoring my texts. On Tuesday 9th/05/2023 I took back the car to Toyota Freeway, and I was told the car will be sent to an electrician so they can further see what the root cause is. Now I get a call from Marvin/Bongani tell me that The electrician says "Before they can dissamble the car further more, I'm gonna have to pay a certain fee however he cannot confirm what thebfee will be". My dispute is Why wasn't the fault picked up the 1st day O took my car in. Did I have to pay for a service that was not sorted and I still need to pay more money? Guys NO, I expected better than this!
