One of my employee’s accounts was inexplicably locked and suspended (?)

Hello.

One of my employees has an account under our companies main amazon account. 2 days ago she received notification from amazon stating that her account was temporary locked. They stated as “You may have provided inaccurate information to Amazon, or used your Amazon account in violation of our conditions of use.” as the reason for the lock.

To the best of her and my knowledge she has not done anything against TOS. Furthermore no other employee account in our company has been effected, include my own admin account.

I had replied to the notification she received asking Amazon to give us a status of her account and to tell us how it can be unlocked. They replied 24 hours later stating that after careful investigation her account would stay locked without giving us any more detail as to why, or what was done in the first place to cause this.

Recap:

1. Employee’s account was locked and seemingly suspended for no reason that we are aware of
2. Main admin account and other employee accounts are fine
3. Amazon is not telling us what happened here, or what we can do to resolve this.

has anyone been in a similar situation, and can you provide any guidance? This is beyond bewildering and I simply cannot see a reason for it. I have not tried creating her a new account yet until I exhaust all other avenues or escalations.
