I got an important phone call back in May of last year, from a family member that I lost contact with for 10 years. I gave her the wrong email of mine and that phone number is the only way I have of contacting them. Their phone number is unlisted, but I need to contact them again, and I've gotten a new phone since, and I did not save the number. Is there any way I can get this phone number? Can I ask AT&T to trace my phone records back to May?
