I got the same message from them as Bastiaan; just checked and there is still no bunq in the iDEAL list. Not sure what they did since they did say it was added...
I've checked the integration rules on how it is said and they need to do this request at least once a month; "If the Issuer list has changed, the latest version has to be saved and used for any subsequent transaction. Acquirers will normally also inform all Merchants (e.g. by email) about changes in their Issuer list. The Directory protocol should at least be executed once a month" So they both weren't informed and they clearly never do this call and have made some crappy integration if they cannot follow basic instructions.
Also e-mailed Currence earlier this week with some questions on how they deal with this on their end, but they didn't answer any of my questions and just asked which shop and that they will inform them... The ticket I created with Ubisoft wasn't even looked at since I created it.
So this is what it seems like to me based on the information that I have (please correct me if I'm wrong): bunq has no way to resolve it, Currence and Ubisoft don't seem to care that much that Emergent Payments has a wrong integration. Too bad I don't believe in any God because it seems like all we can do is pray here.
