Oranje Toyota Klerksdorp useless dealership

What a useless dealership... I bought a second hand Chev utility at Toyota Klerksdorp. When I got bakkie it was not serviced, Engine light came on everytime I put diesel in. They came to fetch the bakkie from my place and held it at Toyota for 2 weeks. When I received it back booklet was still not stamped that it was serviced and engine light came on again after putting in diesel. SO WHAT DID WHO DO WITH MY VEHICLE IN 2 WEEKS TIME???? Now they want to come fetch my bakkie again in the Eastrand and go service it in Klerksdorp.
