Zoom pro purchase error

Hi,
I'm having trouble on purchasing zoom pro. It's saying that "Something went wrong. Please make sure that your billing information is updated, and pop-up blockers are disabled in your browser." I've checked all this. But, still the problem continues. Also I've already purchase a zoom pro to my another zoom account with same bank account. That payment was success. But,  having trouble on this account. Would you please tell me a way to solve it.
