Horrible service with ZERO management feedback.

I took my Mazda CX3 in for it's 24 month service. The car was totally overfilled with oil. They had to drain out oil twice to get the level correct. I mailed them on the 20th of January but not the service manager or dealer principal contacted me as yet. Management's commitment is clearly visible right down to the shop floor. Pathetic to say the least. Lovely car sold by incompetent people.
