Suspension Due to High Volume of Insufficiently Researched Reimbursement Requests

My (US) Amazon seller account was suspended nearly 7 years ago (November 2016). The suspension email received mentioned, ” You have submitted a high volume of insufficiently researched or prematurely submitted reimbursement requests to Seller Support. This is against our policies. As a result, you may no longer sell on Amazon.com, and your listings have been removed from our site.”. I sent 2 appeals back in late 2016 without any positive response (“We looked over your account and the information you provided, and we have decided that you may not sell on Amazon.com.”). The cases they are referring to were automatically opened by Amazon’s own tool that tells you if you have items eligible for reimbursement. I am having an issue finding a way to get this account unsuspended as I am not seeing much info on the suspension reasoning. I am hoping that other people have seen this issue.
