Record keeping is very important, especially with recent calls. I'm sure that we can partner together and get this working for you once again. May I ask is the device saving any calls made or received on the phone? Also, what software and build version do you have installed on the Droid Razr? Can I assume that you are not using a 3rd party app with the call log or calling functionality? As you share the details of the issue then we can get this resolved. I'm looking forward to your reply.
