@Walksalot, go to Settings > Applications and find Google Play Services. Click to enter the app settings and press the button Uninstall Updates. Follow what it says and assuming you have Lollipop installed (Android 5.0.2) you'll end up having the native version of the app: 6.7.77
There is a chance this button is greyed out, not allowing you to click on it. That means this app is managed by Android Device Manager and you have to revoke the rights back to you.
This is done from the Device Administrators page: Settings > General > Security and uncheck the box next to Android Device Manager. After that, go back to Google Play Services app and the button to uninstall updates will be available.
Don't forget to disable auto updates for the app from Google Play Store. If you forget to do that, the app will be updated again to the latest version and you'll be in the same position.
Note that there are other apps depending on google play services version, like YouTube, Google Play Music and others. These apps will stop playing unless they are rolled back to their original version as well. No problem, you follow exactly the same steps for these apps also.
I hope this makes sense.
