How can I request a log or history of my call logs?
simply the number that called and the date.
Was it recently? If so it may still be in your 'calls received' log in your phones call log history, unless you tend to delete your call logs frequently. Phones will keep a 'call history log' of calls dialled/received/missed calls for a certain length of time/certain amount of calls are logged .... all depends on what phone model you have
