I worked at a big name health insurance company that did the same. You would have to give them an email, wait a week, then give them a call to get them to do anything. You could not install anything yourself, it was always a person that remote into your computer. After a month, I still didn’t have visual studio installed when they wanted me to work on some .Net. Then they installed the wrong version of Visual Studio. So the whole process had to be restarted.
I got a new job within 3 months and just noped out.
