楼主这个没有办法了啊，确实是真实关联。
A账号救不回来的情况下，只能尝试采用否认关联来解决：
下面有一份之前用于US的申诉信：
Hello! Thank you for your timely reminder of risk issues in our business. Now in order to solve the problem that exists in the account, we have conducted a deep discussion and investigation on this.
 
Investigation concluded: My account was disabled in error.
I request that my account be reinstated, please see the instructions I submitted for details.
 

On March 1, 2022, I was notified that my account was disabled due to linking, and I immediately contacted the Account Health team, who directed me to troubleshoot the following possible linking issues:
1. Our company received the registration invitation from the investment manager on February 11 this year. I completed the video verification and postcard verification, and I did not complete the creation of my Amazon account until February 31. This is my first time to register for Amazon. (Please see the evidence I have submitted)

2. Since Amazon is a new business developed by our company, only one employee has been hired to be fully responsible for the management and operation of this account, and no personnel changes have been made so far. (please see employment contract)

3. Since January, our company has been solely responsible for the entire process of product selection, procurement, and operation by one person. (Please see Procurement Billing)

4. Since the registration of the account, our account has been logged in on one computer, and the computer has not been changed. Computer IP: XXXXX. (Please see IP screenshot evidence)

5. Through the clues provided by the account status team, we found that my judicial person: XXX, and also served as a supervisor of XXX City XXXX Co., Ltd., but XXX company is a sole proprietorship of natural persons, and XXX does not hold shares, nor is it a beneficiary, So it's not against Amazon's policy.

6. Our company's business license, legal person identity and address prove that all information is true and valid, and the office environment is independent, so there is no false information or account information leakage. (Please check the company address proof, legal person address proof)

The above-mentioned evidence, including the evidence, is true and valid, and our company can take the relevant legal responsibility.
As a professional seller of Amazon, our main source of income is Amazon. We will read all policies and regulations on the platform and consciously abide by these policies and regulations. We hereby confirm that we will never violate Amazon's policies, regulations, terms, etc. any action.
It is confirmed that this time is wrongly disabled, if you need other cooperation, please instruct.
Request to restore our account again.
