I know she has to be wrong but that's what she told me several times. I agree 100%, clicking the box for receiving the code via text or email should never cause this to happen. I tried telling that to her but she kept insisting this is equivalent to changing a phone number or email.
No, I am 100% sure I have not changed anything. I have used the same email and phone number for longer than I can remember. I even verified with her that they did not change. I didn't change anything on my account except make a booking.

Beyond how ridiculous this situation is, how can it be that I can't talk to someone who can verify me and then reset my account now so I can make some bookings? I have a trip to Japan and Korea in less than a month and I want to book rooms. I can use my phone but I'm worried I'm going to get locked out there too.
