Lying, unreliable and bad service

Hi! I'm very very furious with Hailbusters panel beaters in Pietermaritzburg. On the 21st March 2015 I took my car to them for repairs after hail damage where they had to change the lights, windscreen and sort out few dents on the body. They told my insurance company that the job will take 8 working days which then turn into weeks and now months. I've phoned them several times and all the time I get told my car is waiting to be painted. They will not even allow me to see it so I can see if there's any progress. All the time I get told its in the warehouse which is located on another place. So for two months I don't have a car and no one can explain to me the real problem or hold up. They just won't allow me to see my car and always make excuses
