Horrible service from supertech Newcastle

I gave supertech Newcastle my car a polo vivo on the 24th of August for panel Beating on the rear right side. And when ever I call them to check if my car is ready they giving me stories. And they given me 3 deadlines already. When I call they will reschedule and say they are waiting for parts. Last week I called them they said they finished fixing the car what's left if for painting. When I get there on the 8th of October to fetch my car I only find that they just started fixing its not ready. 😡
