Always issues. There is always some issue with their systems so they don't correctly send data to other providers. It has happened with their integration with Storebæltsbroen in Denmark. And this summer I also experienced huge issues using my bizz provided by Øresundpay in Norway. The Norwegian systems simply said that it was an "illegal bizz type".

So yeah, I definitely cannot recommend having a bizz from Øresundpay.

They might as well close their customer support: I actually think that would improve the situation, as the current customer service is worse than having none.
