Some times our customers are charged 2 times for the same invoice - due to integration issues with QuickPay, I guess.

However, we are not notified about this. Even though we now can see the double payment, when we check in Simplero - and return the money - when the customer notifies us about it.

It would be very helpful, if we could get a notification email, whenever there is an issue like this we have to address. It makes customers very nervous that they have to find out about problems like that themselves.
