Never mind, topic was resolved. I changed for another credit card and it worked. By the way, I used the same credit card very recently and everything was fine. So it seems it is only Public Mobile that is not accepting it.
Did not received a clear warning about why I was without service, though, and for a company like a phone provider to not have a number to reach out is really a critical issue. And no message in the page indicated the error in the card, either. So, it would be a nice improvement to Public Mobile to improve the support access or the message services: I really expend the entire day without have a place to do a better consultation, without a phone number of the support to call and in the route. In the most critical moments, I could not count with this company, unfortunately.
