The possible reason why the payments you accepted is on hold is we are still reviewing it. We periodically review payments to ensure everything is alright. This is for the benefit of everyone involved in the payment process.
Since the payment is on hold for two months, you can check your email account for any messages sent by our team. Just make sure to open the email address you use to sign in to the Merchant Service Center.
Read the email carefully. It will give you specific steps to fix any issues. Usually, we ask for more info so we can complete our review. For example, we may ask you to send us a copy of the original invoice you sent to your customer.
Then, follow the steps in the email as soon as possible. Once we have everything, we can usually complete our review within 2 business days. After the review, we can finish processing the payment.
