Broken parts

They replaced my window on the 2 January 2019, there was a defect with the window they should have phone me to replace the window. They took about 3 to 4 hours to replace my window. They never phone me I always had to phone them to find out if the window has arrived. I phoned on Friday 29 March 2019 they advised that I can come in on Monday the 1 April 2019. I arrived there before 12 o'clock,they took my door panel off to replace the new Window, after an hour and half they advise me that my electrical window switch was broken out of the pannel. According to them they haven't broken the switch out. They only unplugged the switch out so they can replace my window... Only Commercial Auto Glass worked on my door in the 8 years that I had my car. They went back on the job cards and nothing was reported in January 2019. On Monday all of a sudden the switch was broken. They phoned me today 2 April 2019 to tell me that it is not there problem.
