I am having that experience right now with Google Apps Mobile Device Management. I turned it on to do some testing, didn't realise that it 'autoenrolled' phones with existing accounts on that domain (There is a separate section for signing up phones that it looked like you had to go through). Now I've unticked every 'enable' box and tried to purge MDM from everywhere I can find it, but it still has the affected phones demanding to be signed up. I've lodged a support ticket, because there's a 'turn on' option, but doesn't seem to be a 'turn off'...
Similarly, if you have Apps for Business like we do, you don't get to see the history of your support cases - that's in the Google Enterprise Support Centre, which becomes available when your user count reaches 100. They did enable it when I asked for it, but it's just very odd that you can have a paid service like this, yet not see your case history unless you're 'big enough'. I don't understand why the case history triggers on '100 users' rather than 'is paying us money'.
Overall GApps is nice... but there are a lot of rough edges and corner cases.
