There are many ways to pay, review this attached help article for all the details:

EDIT:
@Bernardo8Bm By just writing "payment", you could mean for ongoing services or for suspended services or as a new customer activation.
All these possibilities may result in different options for you to try depending on what your attempting.
It's also a good idea to let us know what you have tried so far, what worked and what didn't, so we don't repeat suggestions.
One of the main concerns with accessing self-serve on the site is its horrible caching issues.
Before logging into self-serve, open an Incognito or Private tab, then login.
