I'm experiencing a double payment registration problem.
The customer pays the correct amount using MultiSafePay (a Dutch PSP), but in Magento it shows double of the amount due as the amount paid.
Strangely, this doesn't happen on all payments using this PSP. For now, it has been recorded when using the Maestro gateway.
Any ideas where I should look to investigate this? Any other user with this issue?
Thx,
Dirk
