Billed every month yet I cannot access my account.

I am so disappointed that I have been paying for showmax for months with no access. Firstly the introduction of the new app which has been a disaster, I cannot watch on my tv anymore. Continued to watch on my cellphone which broke last week, bought a new phone and every time I try to login I get a message that my login details are not recognized. How when I'm billed every month?
