I am extremely confused

on 10th dec i received a strange email stating my charge card has been changed as per my request
(i did not request any change)
i opened a case explaining that this was not me.
the case response was just repeating the first email. the status of the case says “transferred”

then on 11th ( i have only just seen this ) i received the following email

Hello,

im not sure if these are linked issues as they appeared at the same time
in any case i dont believe i have violated amazons policy’s as detailed above
i have no idea why this email has been sent.
my account is showing as “at risk” and 1 warning sent

the only other issue i have had was a product violation for “potential trademark miss use”
this was on an asin that i did not create and appears to have been a logo used in a product image
i placed a removal order as i only had a couple of these in fba this was a product that i have approval to sell.

i always try to stick to all policies and have certainly never done anything like has been indicated in the email

any help would be greatly appreciated

Dave H
