Can I really do this #2

[Dtrmned]

So, I had to do a factory reset since I messed up and did the new security measures wrong on my phone. Lost all my pictures unfortunately, but that was about the extent of the damage. While walking through, carrier went to just reverify my information and asked who was authorized to make purchases on the account. My account, and I had added W as an authorized person. Went ahead and took her off so she couldn't buy, upgrade, or bind us to something else. Unfortunately, they immediately sent her a text to that affect.
She texts and mentions that "whatever that means, I was removed". She said then "why don't you just call and set up the mediation appointment it would be easier". Responded back and totally answered and asked another question. Let her do it!
