How do I update my billing details?

i have sent out several emails about my updated credit card info so I do not lose my forms. No one has gotten back with me. Both on my phone and desktop nowhere on the site have I been able to find billing update payment options. I clicked on the left hand corner icon. There was nothing. If someone can please get back with me ASAP so I do not lose everything!!!
