The project got changed

I started working on XYZ Ads Airing data and the site was down after mailing to support I came to know that the dashboard link is updated. But I have not received any news regarding that upon that now I was about to submit my assignment but suddenly seeing that the project has been changed to Impact Car Features. The deadline is same like 16th April. This is so unprofessional. I did one project and now I have to work on again from scratch. This type of unprofessionalism is not expected at all. Now let me know what should I do? Submit the XYZ Ads airing project or the deadline will be extended. I am sorry to say but you guys are not professional at all. Why you will you not notify the enrolled students about the dashboard update? Why will you not inform the students that assignments has been updated?
