Kelston Toyota Cradock doesn't know what they are doing

We have had 3 vehicles serviced in the last 3 months and there have been SERIOUS comebacks with all three of them. One could have resulted in a life threatening situation - something it went in for to fix and around R30 000 'essential repairs' later the vehicle is given back to us - only for it to happen again. Apparently the problem involved the bushes....but then why the HUGE repair. Had a similar situation with another vehicle just before this one. Contacted Kelston, had the local Customer Service person phone me at the beginning of June to say they would get back to me - HEARD NOTHING IN A MONTH. Sent two additional emails to head office in PE - NO RESPONSE. NON EXISTENT SERVICE....
