We use Stripe to process thousands of transactions per month on behalf of retailers.
There are a few hundred refunds per month for returns.
This is working fine with all banks except Monzo. Where the refund consistently shows “Declined” in the Monzo app. This worries the customer, who contacts us. We check with Stripe who find the ARN and prove that the refund, after a few does, has actually gone through.
Stripe say this is a Monzo issue. Example attached (many more where this one came from!)
Any help greatly appreciated.
