Qubuz membership issues

So I have been trying to setup a Qobuz account and the basic name/password stuff is done, but every time I try to enter the billing information, Qobuz comes back with a Whoops message. I have tried two different credit cards on an IPhone, an IPad and a Windows desktop. Per there advise, I tried both Chrome and Safari and have cleaned out the cache on all three devices as well.  
Oh and I contacted the credit card companies and they have never been pinged! 
 

Has anyone else in the US had this sort of problem and if so, how did you resolve it?

Thanks in advance!
