Amazon blocked all BROTHER brand printer listings. Please help !

We have sold many Brother brand printers in the last ten years. No single buyer complains about our product, our product is surely authentic, however Amazon suddenly blocked all listings associated with Brother printers in our account.

We sent the purchase orders/receipts to get approval from Amazon, however Amazon still restricts those listings. NO help from seller support agents.

Please approve the Brother Brand for us. Thank you. Regards,
