You also told them you aren’t the account holder. So that’s pretty much the end of the call right there for any place I have ever worked… I understand your concern and the issue. It just doesn’t work this way technically.
I currently manage a hotel and even as an employee there’s some account information that I am not able to update on a guest’s behalf. They have to do it themselves. The hospitality industry is ripe with fraud and scam attempts. I understand your situation isn’t that, but it would set a precedent for the next situation that IS a scam.
If you really have all her account info and personal data then shit just call and be her. Ask to remove or change your number.
I’m not saying your thing is a scam. I’m explaining how the policies and procedures work and the reason they work that way is because of scams and fraud. Simply put it would be unwise to make changes to any account without confirmation from the account holder. Hope you get it figured out.
