You dont remember the troubles with mBank cards?
Or the mess that happened with WBKs the last time around?
Maybe you should make your customers aware of the WBK TOS...
mBank is not blocking cards as often as they were before, because they stopped issuing them. Besides they have to go through cinkciarz, they can't just lock them straight away. People are reporting that old cards are getting unlocked after contact with support. Everything seems good to me.
I am adding 3 step tutorial that I created, and followed with these cards.
None of mine cards were blocked. And yes, I was using them all over Europe.
I have a lot of questions about these cards every day, and I am 100% honest, I don't care if I sell them, but there are some serious people, who know how to use those, and are willing to pay 45 USD for them.
I can send my history of transaction to people who doubt that I am using these cards myself.
