Service Plan gone bad

My car registration NONOSINC was booked in for service today and because I was at work, I asked my parents to take the car for me, they were dumped tatthe Mimosa Mall and nobody came to fetch them until 18h00pm when they realised that Toyota had clouded and they took a meter taxi back to Toyota to find the car left with the security person and everybody had gone home. This tis total disrespect to my parents and poor customer service, I guess because Toyota are in high demand in S.A. they feel they do not need to provide excellent service, I am totally dissatisfied and disappointed . You've lost a customer, my next car will not be a Toyota if this is the kind of service they provide. Deborah Masego Sebati
