How is this possible Verizon? Account Contact Information Changed Without My Authorization

[Idontunderstand1]

So, I log-in to my Verizon Account and I can see my email address and my telephone number that Verizon verified as the primary contact information.  It says it right there on my account.  However, I am having an issue right now and the chat rep informed me that the person that is the contact, email and telephone number, is the person that I set up with a sub account.

How is this possible?  I didn't authorize this.  Unsurprisingly the chat rep can't fix it and has no explanation.

Of course now the offers that I was supposed to be given when I signed up for Verizon - $100 Verizon gift card, $150 Verizon eGift Card, Chromebook 4 with $100 Samsung credit, and A Google Nest Mini will be sent to the sub-account email because somehow now they are the primary account contact.  Never mind that they will also be receiving verification texts or emails when I am the primary account holder.

Any ideas on my next steps?  FTC?  An Attorney?
