I purchased a Macbook Air 10.11.2 El Capitan back in February 2016. I didn't install any upgrades because I'm satisfied with El Capitan.
When I started having problems earlier this year (2017), I decided to make a clean reinstall of El Capitan. The only option left for me was to download it through Internet recovery so I waited until it finished downloading.
After downloading, it came up with the Recovery mode. I erased the Mac partition and reinstalled OSX. It appears to be different, instead of having El Capitan it gives me the Yosemite version. That's unacceptable to me. I purchased my mac that came with El Capitan but the downloaded version is Yosemite (which I think I was scammed by the store seller).
Is this something normal or something I have to complain about back to the store? Also, Yosemite is giving me an error upon entering my Apple ID, it says that the item is temporarily unavailable.
What should I do now? I need help, and I would appreciate it much. Thanks!
