Worse service ever from PG Glass Pinetown made payment work still not done.......

We have been receiving the worst service ever from the PG glass in Westmead Pinetown. We made payment for our quote on the 20th March 2019 and the job is still not done up to today, and today its the last straw as they are coming back for the 3rd time to do the same measurements they have done 3 times already and they still have not installed the glasses we paid for. It is really ridiculous and annoying , you dont get help even from the offices they do not know what is suppose to be done or what job was suppose to be done.
