I purchased more space on iCloud and it’s still showing the old amount in settings. I did the purchase twice. Is there a support number I can call

Have you tried signing out of iCloud and back in? Has your credit card been charged and have you received an e-mail receipt?

If necessary, contact iTunes Support. Scroll to the bottom of the page in the 2nd link.
