Shoddy Service Allen Joss Mazda Wonderboom

When I had my Mazda's 30 000 km vehicle serviced by Allen Joss Mazda Wonderboom they overfilled my engine oil thank goodness my husband checked my vehicle when I got home or I would have blown the engine thanks to useless Allen Joss MAZDA service's I had to take my vehicle back to drain the excess oil!!!!
