I'll just add to the above comments: As far as I am aware, unless their was either a warant to record the call, or both parties have agreed to the call recording, I don't think it is admissible in a court of law (assuming you mean an actual audio recording of the call). I think it would be illegal for GG to record every single call, and I also believe it is illegal for an individual or organisation to record calls without consent (notice the messages at the beginning of calls to banks etc. telling you the call may be recorded?)
If you just mean records of calls made or received etc. I would suggest asking an agent. They should be able to provide you with that information.
