An Amazon seller claims that Amazon is holding over $4.2 million of their funds due to a 'velocity review' triggered by an increase in Merchant Fulfilled orders. The seller has been selling on Amazon since 2013 with outstanding metrics and averages over $1 million in monthly sales. Despite sending multiple emails to Amazon, the seller has not received any help or disbursal of their funds. This has put their business at risk of not being able to pay employees or continue operating.
