Hi diami2019
We cannot answer this situation in the Community, as we do not have details of the circumstances you have encountered.
As a general rule: if you have a GA that has been deposited and you need to buy a ticket, you have the possibility of manually creating a new customer profile by reversing the first and last names (first name under surname and the last name under first name) or buy a ticket as guest.
For any complaints, I recommend that you contact us by using the contact form.
I wish you a nice weekend.
Kind regards
NicolasK
