PG Autoglass Lies and disinterest

I took my car for a windscreen repair at PG Auto glass Sandton. They kept the car for over 3 months and did absolutely nothing on it.Every week I would phone for progress and they would always LIE to me.Every week was a different story. Eventually after 3 months I went to the branch, my car was covered in a layer of dust and had not been touched. I contacted PG AutoGlass head office and they investigated. Head office then informed me that it is not worth their while to do the job and I must go away.
