The symptom of double charges

[novoselt]

Describe the bug
We regularly have double transactions and thought that the users are impatient. This is from a user who made 3 double transactions in a row (on multiple days, so with big time intervals between them):

The issue I am encountering is not the delay in the transaction processing. It is rather once the transaction gets completed and then it says "finish your payment..." on the purchases tab where you see the "add money money" option. This gives me the perception that the transaction has not gone through successfully and that's why I have to go ahead with finishing the payment for the transaction. When that happens, it charges twice.

To Reproduce
No idea, but hopefully the above is useful for locating the code where something has to change.

There was a support request from a user who didn't try to pay the second time. Impersonating the user indeed I saw the message about finishing the purchase (which actually was not possible without adding more money to the account, maybe the calculation was off because of pending charges) or cancelling it. Trying to finish the purchase asked for payment information again.

Not sure how the UI looked in this case, but here the license was purchased a bit before the second transaction:
