Ford rustenburg failed services

On the 1st August 2019 I brought my car at 7am,for a 105000km service with Ford Rustenburg.I was the first customer to open the gates at 7am. On collection of the car was told Mr Jaku that the technicians didn't make it for work and my car is not ready for collection. Need I mention that all the cars were serviced except mine. Need I also mention that no one took the responsibility to inform me throughout the day, and I only knew upon collection. This was a timing belt service I was told and that it takes two days,was only told upon collection. I have been experiencing a disturbing vibration on the car and I tried to take it to Mafikeng they could not assist, I only managed to bring it back to Rustenburg today. I did call and the lady said I can just bring it for them to see what the problem is. Now Mr Jaku who is the service manager says he cannot promise me if he can assist, he only has an opening on Thursday as his technician are on training. This is the same man whom could not manage the jobs the time I brought my car, scheduled. Need I mention that this is the same dealership I have been servicing with for entire 5yrs of my car. The same guy didn't even test the Car after service and his already saying the could be parts he needs to order. Why is this only coming now on a return job. Was the service not done and now his using this opportunity to milk more money for something that's not there. Now I want Ford rustenburg to do its job fully. Mr Jaku has not even taken responsibility that the mistake I'm encountering is because he didn't do a complete service and testing on the car upon the service.
