Hyundai Malmesbury BAD service

I took my car for a service at Huyndai Malmesbury on 24.11.23..The car never gave us a problem of a day before. After the service the car all of a sudden did'nt start when the key was turned, we need to step on the petrol pedal as well...the pdc sensors also did not work after the service. We took the car back to Huyndai Malmesbury and the technician had a lot of stories obviously. Whereafter the car totaly "shut down" it would'nt start at all. I phoned them and told them what happened and what my expectations are whereafter they promised to come and get my car on 7.12.23 to fix it on 8.12.23 to be returned the same day as they do not have a courtesy car avaiable for me to use. And here I am... still waiting for my car to get picked up. I spoke to the driver of the towtruck yesterday afternoon who told me he was out the whole day he cannot come pick up my vehicle as well...after I argued with him for a while I asked to phone him back in a few minutes, but when I phoned again, literally 2 minutes after our conversation, their landline was switch to voicemail. Unfortunately client service flew out of the window at Huyndai Malmesbury. I am inconvenienced in so many ways... And disgusted in their bad service.
