Worst gateway ever

On the 5th January 2024 i received the payments and paystack started asking me for business review which was supposed to be made during verification of my account and my bank. When its time to payout they asked me for proof of delivery and i provided and they emailed me telling me that they busy with the business review. I delivered the goods but no payment.

Im in south Africa by the way, they also told me that the buyer has reported funds *****ulent and i must send proof of delivery within 24 hours, the customer details otherwise they will refund the customer and i also did and i ask support what have you asked the customer?

How sure are you. Now im at lost my business has stopped because of this, everytime its review review review. Please pay me my money tell give the customer my details if they have a problem.

I dont why do you take and verify our details for and how can a customer buy on Friday and report on Monday.
