Revoking offers just a week before joining! - Software Engineer CompuCom Employee Review

Revoking offer just a week before joining leaving you jobless...not even bothered to reply on your mails...no courtesy for compensation...it is illegal to revoke the joining after acceptance of the offer letter specially in this this time of pandemic when people are coming to help each other they do not bother even to discuss the workaround like many company giving furloughs or something or if you have decided to revoke atleast tell people in advance cuz now I have neither time to search a new job nor rollback the resign and this happened when I was in continuous touch with the company's HR who in every communication not to worry we are working on your onboarding..
