This Item is temporarily unavailable - Mid 2009 MacBook Pro

Earlier today, I received a Mid 2009 15 inch MacBook Pro and I had to reinstall OS X El Capitan, when I went on to do that I got an error saying “This item is temporarily unavailable”. So, I tried changing the date and time, I couldn’t boot into internet recovery mode (it kept showing the apple logo for some reason) and I tried signing into iCloud via Getting help Online but it was taking forever to load. So, I don’t know what else to do. If someone knows, let me know. Thank you.
