New Hire Neglect

I am a new hire who hasn't begun working for Amazon. I applied in mid April and passed the requirements. I got the offer later a week later pending my start date. It is now July and I still haven't received any updates. I went to the application chat and they keep telling me they are working on my start date and to keep checking. I also demanded to talk to HR but they refused because it was a privacy issue, when a company offers your a job they are supposed to provide with a direct contact number and they refused. They need to compensate me for all the time I could have been working.
