I had a worst experience of my life there at the auto service department. I made an appointment for a clean test, and left my car with the store for a whole day. At the end of the day, I went to colect my car, I was told the work was done, and I paid 37 dollors, without check the detail of the service description. By two month later, I found the e-test was not done when I went to renew my licence plate!!
When I went back to the store make enquiry on this and told them it was my last day for renewal the licence, the staff was not helpful at all. The payment I made is only for replacement of a light bulb. They would not admit it was a mistake for not telling me the e-test was not done because their system was down at that day. I will never ever use their service again.
