That is my guess. When I talked with Amazon on the phone, first time in 10 years, they had no clue.
The CC company forwarded me to the fraud department. They only said it fit a pattern of fraudulent attempts they have seen lately. For this reason they froze the account.
They turned it back on after I explained we do work with Amazon.
I passionately (and calmly) explained, what they did. As in “You just shut off access to a major eCommerce channel for us. We can not ship orders, or see orders, if we do not ship we will be suspended. We can not get payments from Amazon without the card active. Principals and the entire team can not get paid. Please turn it back on.”
Like Amazon, they had no clue what I was talking about.
Thanks to the SAS, in a time of slight panic, like landing a plane with one wheel, I completed the mission.
