Getting Yosemite instead of El Capitan 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!
I think You should make clean install of El Capitan from USB. You were not scammed, don't worry. I was in the same situation.
It can be done under one condition - You've updated somewhere in the past to the El Capitan and You can see it in Purchased section in AppStore.
That's nothing complicated, first make sure that You have downloaded El Capitan from AppStore. Than You should make bootable El Capitan USB and clean-install it on Your Mac. Follow these steps on this site:
