Two times in the past year I have received calls from Sprint because someone called to verify an ESN that they were looking to purchase on eBay - but those ESN's were my phones.

At first I wouldn't even talk to Sprint because someone called me and could've spoofed the number, so I had them walk me to through their site to see the number I can call them back at and then be transferred back to them. It was someone within the smartphone activations team.

After the second call I told them I was concerned and they apologized for the worry and "for being cool about it" offered me an extra 1000 minutes/month for life. Well I have a 1500 minutes share plan that now only uses 200 minutes because of AnyMobile. So I told them to apply it to my fathers old 200 minute 20$ legacy plan because he would never answer his phone in fear of using his minutes.

So, don't know if this is the kind of experiences you were asking for but hope it helps.
