Need Satisfactory Video Animation Services

I wanted the high definition explainer video animations so lately I hired a video animation studio but unfortunately I was provided with a very dis-satisfactory service. The team delayed the delivery of the project and then the quality that they delivered was unacceptable for me. I want to have the professional video explainer animation services in Australia from a reputable video animation studio, who must be able to create the perfect video animation for me. It will be very helpful if someone can kindly let me know which studio is the best that can hire to get the qualified services.
